overlookmotel c2c8f806f9 refactor(napi/parser): raw transfer store source text at end of buffer (#22392) ...

Oxlint's raw transfer implementation stores the source text at end of the buffer. Prior to this PR `napi/parser` stored source text at the start of the buffer.

Bring `napi/parser` into line with Oxlint, by also storing source text at end of the buffer.

Making all versions of raw transfer that we use align with each other removes complication (all versions now have the same implementation of `deserializeStr`) and also removes some fragile code where it'd be easy to accidentally trigger UB (see the updated comments in `arena/fixed_size/windows.rs` and `arena/alloc_impl.rs`).

Unfortunately, storing source at end of buffer is slightly less efficient than storing it at the start. We'll switch all implementations to storing source at start of buffer when we move to storing all strings (source text and all other strings) together in a single contiguous block. But in meantime, this slight inefficiency is outweighed by the gain in safety.
