48821c0110 feat(semantic,syntax): add SymbolFlags::ArrowFunction (#4946)
There are many cases in lint rules where we want to see if a symbol is a
function by checking its SymbolFlags. This is currently not fully possible,
since variables assigned to arrow functions are not distinguished from any other
kind of variable. This PR adds `SymbolFlags::ArrowFunction` for variables that
are initialized to arrow functions. Symbols that are re-assigned to arrow
functions will not have this flag, but this is acceptable for lint rules.

03c643a8af fix(semantic): incorrect scope_id for catch parameter symbols (#4659)
When we move all the bindings in the CatchClause scope to its child scope (BlockStatement), we also need to replace the scope_id in the symbol with the scope_id of the new scope.

b952942993 feat(linter): add eslint/no-unused-vars ( attempt 3.2) (#4445)
> Re-creation of #4427 due to rebasing issues. Original attempt: #642
-----

Third time's the charm?

Each time I attempt this rule, I find a bunch of bugs in `Semantic`, and I expect this attempt to be no different. Expect sidecar issues+PRs stemming from this PR here.

## Not Supported
These are cases supported in the original eslint rule, but that I'm intentionally deciding not to support
- export comments in scripts
  ```js
  /* exported a */ var a;
  ```
- global comments
  ```js
  /* global a */ var a;
   ```

## Behavior Changes
These are intentional deviations from the original rule's behavior:
- logical re-assignments are not considered usages
  ```js
  // passes in eslint/no-unused-vars, fails in this implementation
  let a = 0; a ||= 1;
  let b = 0; b &&= 2;
  let c = undefined; c ??= []
  ```

## Known Limitations
- Lint rules do not have babel or tsconfig information, meaning we can't determine if `React` imports are being used or not. The relevant tsconfig settings here are `jsx`, `jsxPragma`, and `jsxFragmentName`. To accommodate this, all imports to symbols named `React` or `h` are ignored in JSX files.
- References to symbols used in JSDoc `{@link}` tags are not created, so symbols that are only used in doc comments will be reported as unused. See: #4443
- `.vue` files are skipped completely, since variables can be used in templates in ways we cannot detect
  > note: `.d.ts` files are skipped as well.

## Todo
- [x] Skip unused TS enum members on used enums
- [x] Skip unused parameters followed by used variables in object/array spreads
- [x] Re-assignments to array/object spreads do not respect `destructuredArrayIgnorePattern` (related to: https://github.com/oxc-project/oxc/issues/4435)
- [x] #4493
- [x] References inside a nested scope are not considered usages (#4447)
- [x] Port over typescript-eslint test cases _(wip, they've been copied and I'm slowly enabling them)_
- [x] Handle constructor properties
  ```ts
  class Foo {
    constructor(public a) {} // `a` should be allowed
  }

d6974d4ff7 refactor(semantic): AstNodeParentIter fetch nodes lazily (#4533)
Refactor `AstNodeParentIter`, which is used to iterate down node ancestry chain. Fetch `AstNode` objects lazily, only when they're required by a `next()` call. If caller doesn't iterate all the way down the chain, likely this will result in 1 less array lookup.

7b5e1f5ac8 refactor(semantic): use is_empty() instead of len() == 0 (#4532)
It's preferred to use `is_empty` where possible. `is_empty` is sometimes slightly more optimized than `len() == 0`.

cf1854be7c feat(semantic): remove ReferenceFlags::Value from non-type-only exports that referenced type binding (#4511)
```ts
type T = 0;
export { T }
         ^ ReferenceFlags::Type | ReferenceFlags::Read
```
The export `T` only referenced type binding. We should remove `ReferenceFlags::Read` for it.

40cafb8c61 fix(semantic): params in export default (function() {}) flagged as SymbolFlags::Export (#4480)
The code changes in `builder.rs` optimize the export flag check in the `SemanticBuilder` implementation. Instead of setting the export flag to `true` for all cases except `ExportDefaultDeclarationKind::ClassDeclaration(ref class)`, the flag is now set to `true` only for `ExportDefaultDeclarationKind::ClassDeclaration` and `false` for all other cases. This change improves the efficiency of the export flag check.

ccb1835a45 refactor(semantic): methods take Span as param, not &Span (#4470)
`Span` is `Copy` and 8 bytes. So better to pass `Span` to functions, rather than `&Span` (which is also 8 bytes, but involves the indirection of a reference).

c99b3eb464 refactor(syntax): give ScopeId a niche (#4468)
Make `ScopeId` a type with a niche, like `SymbolId` and `ReferenceId`. This makes `Option<ScopeId>` 4 bytes instead of 8, and shrinks various AST types e.g. `ArrowFunctionExpression` by 8 bytes, and halves the size of the `Vec` in `ScopeTree::parent_ids`.

The snapshot change on `prefer-hooks-in-order` lint rule appears incidental - it doesn't alter what errors are reported, only the order they're reported in. This appears to be because it changes the order of keys in a hashmap keyed by `ScopeId` that [the rule uses](a49f4915de/crates/oxc_linter/src/rules/jest/prefer_hooks_in_order.rs (L143)).

348c1ade96 perf(semantic): remove span field from Reference (#4464)
Remove `span` field from `Reference`. Span can instead be got via looking up span on `AstKind` via `reference.node_id`.

This shrinks `Reference` from 20 bytes to 12 bytes.

It does make getting span of a `Reference` a bit slower, as there's an extra table lookup involved, but the only places this is needed is in linter, and almost always when generating a diagnostic (i.e. cold path).

6a9f4db609 perf(semantic): reduce storage size for symbol redeclarations (#4463)
Most symbols don't have redeclarations.

So instead of storing `Vec<Span>` directly in `redeclare_variables` (24 bytes per symbol), store `Option<RedeclarationId>` (4 bytes).

`RedeclarationId` indexes into `redeclarations` where the actual `Vec<Span>` is stored. But for symbols with no redeclarations (the vast majority), it takes 4 bytes per symbol only.

f17254ae2a refactor(semantic): populate declarations field in SymbolTable::create_symbol (#4461)
`declarations` field of `SymbolTable` is part of SoA group, where all `Vec`s in the group are indexed by `SymbolId`. Populate `declarations` field along with the rest in `create_symbol`, to prevent them getting out of sync. This will prevent bugs like the one fixed in #4460.

ac08de817e fix(linter/react_perf): allow new objects, array, fns, etc in top scope (#4395)
Consider the following code:
```tsx
import { FC } from 'react'
import { SvgIcon } from '@mui/material'

const StyledIcon = <SvgIcon sx={{ padding: 1, color: '#ff0000' }} />
//          reported violation  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
export const MyComponent: FC = () => {
    return (
        <div>
            {StyledIcon}
            {/* ... */}
        </div>
    )
}
```

This should not be a violation since the JSX is pre-computed and re-used, which
does not break React's `Object.is()` checks.
