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!
