Add setting to disable the git apply step in test patch (#22130) (#22170)
Backport #22130

For a long time Gitea has tested PR patches using a git apply --check
method, and in fact prior to the introduction of a read-tree assisted
three-way merge in #18004, this was the only way of checking patches.

Since #18004, the git apply --check method has been a fallback method,
only used when the read-tree three-way merge method has detected a
conflict. The read-tree assisted three-way merge method is much faster
and less resource intensive method of detecting conflicts. #18004 kept
the git apply method around because it was thought possible that this
fallback might be able to rectify conflicts that the read-tree three-way
merge detected. I am not certain if this could ever be the case.

Given the uncertainty here and the now relative stability of the
read-tree method - this PR makes using this fallback optional but
enables it by default. A `log.Critical` has been added which will alert
if the `git apply --check` method was successful at checking a PR that
`read-tree` failed on.

The hope is that none of these log.Critical messages will be found and
there will be no significant difference in conflict detection. Thus we
will be able to remove the git apply fallback in future, and/or improve
the read-tree three-way merge method to catch any conflicts that git
apply method might have been able to fix.

An additional benefit for anyone who disables the check method is that
patch checking should be significantly less resource intensive and much
quicker.
