Pass "-Xgc:CMC" to dex2oat when userfaultfd GC is enabled.
This change is a no-op change. It doesn't enable userfaultfd GC by
default. ENABLE_UFFD_GC=true can be passed to the build system to enable
userfaultfd GC for testing purposes.
Bug: 242553398
Test: -
1. lunch aosp_oriole-userdebug
2. ENABLE_UFFD_GC=true m
3. See "--runtime-arg -Xgc:CMC" in .invocation files.
