The sourcemap implement port from
[rust-sourcemap](https://github.com/getsentry/rust-sourcemap), but has
some different with it.
- Encode sourcemap at parallel, including quote `sourceContent` and
encode token to `vlq` mappings.
- Avoid `Sourcemap` some methods overhead, like `SourceMap::tokens()`
caused extra overhead at common cases. Here using `SourceViewToken` to
instead of it.
Export `SourcemapVisualizer` from codegen, it will be used oxc and
rolldown sourcemap test, so it support multiply source print, it will
using sourcemap `sourcesContent` as original source.
This gets all the new TS types working to the same level TS output was
before and fixes a bunch of other codegen

- Adds option to `CodegenOptions` - `enable_typescript` to enable output
of TS.
- Stops skipping output that is TS when `enable_typescript` is enabled
- Adds TS support to
- Function
- FormalParameter
- BindingPattern
- Adds basic tests for TS generation

The runtime performance gains does not out weight the compilation speed from
building the custom allocators, which takes about a minute to build on
slower machines.

Submodules are a blocker for beginners, we should make it clone on
demand.
It is also a blocker for people who wants to target this repo as a crate
for testing purposes, cargo will do a full clone if you specify
oxc_parser = { git = "this repo" } in Cargo.toml

HIR is removed from this PR, with the minifier being commented out.
HIR is a wonderful idea for compiling to lower languages, but after
sitting on it for a few months I found that it only adds confusion and
uncertainties to both myself and future contributors.
It also adds too much burden to maintainers if we plan to support more
downstream tools.
1 AST is the only way.
Fold constant addition expressions. Handles string concatenation and
addition, both with implicit casting.
For example,
```ts
let x = 1 + 1
let y = "hello " + "world"
```
now becomes
```ts
let x = 2
let y = "hello world"
```
## Extra Goodies
- test(minifier): add `test_snapshot` helper to perform snapshot tests
with `insta`
- up(hir): implement `std::ops::Add` for `NumericValue`
- up(span): impl `TryFrom<Cow<'_, &str>>` for `Atom`
