perf(transformer/jsx): speed up decoding `JSXText` strings (#9741) close: #10249 Speed up transforming `JSXText` nodes by: 1. Avoiding allocations (construct strings directly in arena, with no intermediate `String`s). 2. Where no HTML entity decoding or string concatenation is required, reuse a slice of source text, rather than generating a new `Atom` and copying string data.
