`AstBuilder::move_assignment_target` pass a static `Atom` instead of empty string to `AstBuilder::simple_assignment_target_identifier_reference`. This avoids a call to `alloc` to allocate an empty string in arena.

The `CalculateSignatureKey`is used to collect signature keys, but since it requires a double visit, it doesn't perform very well. Now I use ScopeId to store the signature key that is generated in `CallExpression`. This way we can then determine which ArrowFunction/Function the `CallExpression` belongs to.
Follow-on after #5223. We're trying to ignore JSX identifiers, so there's no point walking downwards from `JSXElementName`, as all we'll find is JSX identifiers that we want to ignore.
Follow-on after #5223.
Now that we are getting an `IdentifierReference` with a `reference_id`, we can use that ID for a faster lookup of whether the reference is bound or not.
Outside of the parser, a `JSXIdentifier` in a `JSXElementName::Identifier` will never be a identifier reference. So move the code for deciding if a `JSXElementName` is `JSXElementName::Identifier` or `JSXElementName::IdentifierReference`, and the code for converting from one to the other, into the parser - which is only place it should be used.
#5223 added a new variant `JSXElementName::IdentifierReference` for JSX identifiers which are treated as references (e.g. `<Foo>`) as opposed to `JSXElementName::Identifier` which is for lowercase (e.g. `<div>`).
But we were incorrectly categorizing identifiers beginning with `_` or `$` - these should also be treated as references.
(as discussed in https://github.com/oxc-project/oxc/pull/5339#issuecomment-2321037779)
Follow-on after #5223.
#5223 introduced the line `let span = jsx_el.opening_element.name.span();`. But the span is only needed when creating a diagnostic when the rule fails (cold path). Avoid the work of getting the span for the common case where the rule passes.
Follow-on after #5223.
JSX identifiers which start with a capital letter are now `JSXElementName::IdentifierReference`s, so no need to check for capitalized `JSXElementName::Identifier`s.
Box `TSThisParameter` in `Function`, `TSMethodSignature` and `TSFunctionType`. I assume `function(this: Whatever) {}` is a fairly rare syntax in TS code, and obviously never occurs in JS code, so it takes up a lot of space in `Function` for this uncommon case.
This change reduces `Function` from 136 bytes to 104.

`TraverseCtx::ancestors` iterator would previously yield `Some(Ancestor::None)` before finally yielding `None`. Skip `Ancestor::None` as it's pointless.
Change meaning of `level` passed to `TraverseCtx` from "levels above current" to "levels above parent". `ctx.parent()`'s equivalent was `ctx.ancestor(1)`, now it's `ctx.ancestor(0)`.
This prevents out of bounds read on `ctx.ancestor(0)` (UB), which was made possible by #5286.
Preparation for upstack PRs. Graphical reporter diagnostics look exactly the same. This does, however, change `to_string()` to only show diagnostic messages, and not error codes + messages.
This pr is for jest/vitest compat and add another jest rule condition

changes from using `without_parenthesis` to using `get_inner_expression` to ignore type casts, non null assertions ect.
this helps catch more error cases
