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

437e15bae5 Replace catch bun.outOfMemory() with safer alternatives (#22141) 
Replace `catch bun.outOfMemory()`, which can accidentally catch
non-OOM-related errors, with either `bun.handleOom` or a manual `catch
|err| switch (err)`.

(For internal tracking: fixes STAB-1070)

a57dee5721 Various safety improvements (safety.ThreadLock, stack traces, MimallocArena, RefCount, safety.alloc) (#21726) 
* Move `DebugThreadLock` to `bun.safety`
* Enable in `ci_assert` builds, but store stack traces only in debug
builds
  * Reduce size of struct by making optional field non-optional
* Add `initLockedIfNonComptime` as a workaround for not being able to
call `initLocked` in comptime contexts
* Add `lockOrAssert` method to acquire the lock if unlocked, or else
assert that the current thread acquired the lock
* Add stack traces to `CriticalSection` and `AllocPtr` in debug builds
* Make `MimallocArena.init` infallible
* Make `MimallocArena.heap` non-nullable
* Rename `RefCount.active_counts` to `raw_count` and provide read-only
`get` method
* Add `bun.safety.alloc.assertEq` to assert that two allocators are
equal (avoiding comparison of undefined `ptr`s)

(For internal tracking: fixes STAB-917, STAB-918, STAB-962, STAB-963,
STAB-964, STAB-965)
