upload: add --ignore-remote-commitsv2.72stable

When uploading a branch that merges another remote-tracking branch (such
as an upstream branch into the destination branch), ReviewableBranch
only excludes the destination tracking branch (^base). As a result, git
rev-list walks the merged parent and counts all merged commits even
though they already exist on a remote branch, triggering the unusual
commit count warning in _VerifyPendingCommits.

Add --ignore-remote-commits to `repo upload` to pass --not --remotes to
git rev-list in ReviewableBranch so commits already reachable from
refs/remotes/* are excluded from the pending commit list.

Test: ./run_tests tests/test_project.py tests/test_subcmds_upload.py
