Subject: add sanitizer options to xmake (#847)

- Improvement: Add easy access options for sanitizers with `xmake config` and `xmake test` as options
  - `--msan=[y|n]` Enable MemorySanitizer (Linux only, requires all deps instrumented)
  - `--asan=[y|n]` Enable AddressSanitizer (disables mimalloc and sentry)
  - `--tsan=[y|n]` Enable ThreadSanitizer (Linux/Mac only)
