Cache repository default branch commit status to reduce query on commit status table (#29444)

Browse source 
After repository commit status has been introduced on dashaboard, the
most top SQL comes from `GetLatestCommitStatusForPairs`.

This PR adds a cache for the repository's default branch's latest
combined commit status. When a new commit status updated, the cache will
be marked as invalid.
