Core Changes

• Turbopack: Update to swc_core v50.2.3 (#​87841) (#​88296)
  • Fixes a crash when processing mdx files with multibyte characters. (#​87713)
• Turbopack: mimalloc upgrade and enabling it on musl (#​88503) (#​87815) (#​88426)
  • Fixes a significant performance issue on musl-based Linux distributions (e.g. Alpine in Docker) related to musl's allocator.
  • Other platforms have always used mimalloc, but we previously did not use mimalloc on musl because of compilation issues that have since been resolved.
