As a member of github.com/orgs/llvm/teams/pr-subscribers-llvm-mc , I was not notified about PR #<!-- -->149935.

This commit introduces the `llvm:mc` label to cover the generic MC
interface, excluding target-specific MCTargetDesc files.

- Rename the `mc` label to `llvm:mc` for consistency with other LLVM subdirectory labels.
- Exclude `llvm/test/MC` from the label scope, as it contains many target-specific directories.

Admin: please change the name of https://github.com/orgs/llvm/teams/pr-subscribers-llvm-mc
to "pr-subscribers-llvm:mc", similar to pr-subscribers-llvm:ir
