05d0475c6c Update to zig 0.15.2 (#24204) 
Fixes ENG-21287

Build times, from `bun run build && echo '//' >> src/main.zig && time
bun run build`

|Platform|0.14.1|0.15.2|Speedup|
|-|-|-|-|
|macos debug asan|126.90s|106.27s|1.19x|
|macos debug noasan|60.62s|50.85s|1.19x|
|linux debug asan|292.77s|241.45s|1.21x|
|linux debug noasan|146.58s|130.94s|1.12x|
|linux debug use_llvm=false|n/a|78.27s|1.87x|
|windows debug asan|177.13s|142.55s|1.24x|

Runtime performance:

- next build memory usage may have gone up by 5%. Otherwise seems the
same. Some code with writers may have gotten slower, especially one
instance of a counting writer and a few instances of unbuffered writers
that now have vtable overhead.
- File size reduced by 800kb (from 100.2mb to 99.4mb)

Improvements:

- `@export` hack is no longer needed for watch
- native x86_64 backend for linux builds faster. to use it, set use_llvm
false and no_link_obj false. also set `ASAN_OPTIONS=detect_leaks=0`
otherwise it will spam the output with tens of thousands of lines of
debug info errors. may need to use the zig lldb fork for debugging.
- zig test-obj, which we will be able to use for zig unit tests

Still an issue:

- false 'dependency loop' errors remain in watch mode
- watch mode crashes observed

Follow-up:

- [ ] search `comptime Writer: type` and `comptime W: type` and remove
- [ ] remove format_mode in our zig fork
- [ ] remove deprecated.zig autoFormatLabelFallback
- [ ] remove deprecated.zig autoFormatLabel
- [ ] remove deprecated.BufferedWriter and BufferedReader
- [ ] remove override_no_export_cpp_apis as it is no longer needed
- [ ] css Parser(W) -> Parser, and remove all the comptime writer: type
params
- [ ] remove deprecated writer fully

a72d74e09a Split JS parser into multiple files (#20880) 
Splits up js_parser.zig into multiple files. Also changes visitExprInOut
to use function calls rather than switch

Not ready:

- [ ] P.zig is ~70,000 tokens, still needs to get smaller
- [x] ~~measure zig build time before & after (is it slower?)~~ no
significant impact

7a31108019 Implement expectTypeOf (#21513) 
Fixes #7569 

This adds expectTypeOf, but not the experimental `--typecheck` flag from
vitest. To use it, you need to typecheck manually with `bunx tsc
--noEmit` in addition to `bun test`

712d5be741 Add safety checks to MultiArrayList and BabyList (#21063) 
Ensure we aren't using multiple allocators with the same list by storing
a pointer to the allocator in debug mode only.

This check is stricter than the bare minimum necessary to prevent
illegal behavior, so CI may reveal certain uses that fail the checks but
don't cause IB. Most of these cases should probably be updated to comply
with the new requirements—we want these types' invariants to be clear.

(For internal tracking: fixes ENG-14987)
