Filters for GetAllCommits (#24568)

The `GetAllCommits` endpoint can be pretty slow, especially in repos
with a lot of commits. The issue is that it spends a lot of time
calculating information that may not be useful/needed by the user.

The `stat` param was previously added in #21337 to address this, by
allowing the user to disable the calculating stats for each commit. But
this has two issues:
1. The name `stat` is rather misleading, because disabling `stat`
disables the Stat **and** Files. This should be separated out into two
different params, because getting a list of affected files is much less
expensive than calculating the stats
2. There's still other costly information provided that the user may not
need, such as `Verification`

This PR, adds two parameters to the endpoint, `files` and `verification`
to allow the user to explicitly disable this information when listing
commits. The default behavior is true.
