  [NFC][sanitizer] Commit test for #106912 (#108289)

Almost all sanitizers already support the test.
* Tsan does not use DlsymAlloc yet.
* Lsan will support with #106912.

memprof,rtsan,nsan are not tested as part of
sanitizer_common, but we should keep them here to
show up when it happen.

  -----------
  [lsan] Fix free(NULL) interception during initialization (#106912)

Previously an attempt to free a null pointer during initialization would
fail on ENSURE_LSAN_INITED assertion (since a null pointer is not owned
by DlsymAlloc).
