perf(transformer/react-refresh): reduce allocations (#8018) Small optimization. When generating hash of hooks key, build the hash string directly in arena, avoiding an intermediate heap-allocated `String`, by using `base64` crate's `encode_slice` method which writes directly into a slice. `base64` crate is rather inefficient - there are various optimizations that could be made. But not worth getting into that, as this is only place we use `base64` crate in a performance-sensitive context.
