repository: Remove `IsSquashInProgress()` RPC
In release 14.2, we have converted UserSquash()
to never use worktrees
anymore. As a result, the old IsSquashInProgress()
RPC doesn't really
do anything anymore and always returns the equivalent of false
.
Upstream has thus been converted in b5b78c33c9f (merge_request: Drop
checks whether a squash is in progress, 2021-08-20) to not use the RPC
anymore, leaving it without callers.
Remove IsSquashInProgress()
.
Closes #3728 (closed)
