perf(sourcemap): use simd to escape JSON string (#4487) 
Also optimize the memory allocation in string escape. The default size in `serde_json` is 1024 for String type, we pre allocate `string.len() * 2 + 2` for every string to reduce re-allocate in escaping.

I've tried to hand write SIMD implementation, but it's too complex, so I uses the `v_jsonescape` here. But it doesn't support `aarch64` and `wasm32` simd implementation, we need to contribute to it!

The sourcemap implement port from 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().
