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

### What does this PR do?
The `then` function in `transpiler.transform` can cause GC, which means
it can cause the `Transpiler` to become freed, which means that if that
same transpiler is in use by another run on the other thread, it could
have pointers to invalid memory.
Also, `ESMCondition` has unnecesasry memory allocations and there is a
very tiny memory leak in optionsFromLoaders
