localrepo: extract loading of hgrc files to standalone function

Various 3rd party extensions supplement where per-repo config data
lives. Looking at their sources, they resort to unorthodox means to
inject the config data. And the way they do it is susceptible to
corner cases. e.g. not processing automatic extension loads,
not reacting to new or disabled extensions in configs, etc.

This commit extracts the core logic of loading hgrc files into
a standalone function so there is a clear function that can be
monkeypatched to inject per-repo config data at repository open
time.

If you can't run the entire testsuite for some reason (it can be
difficult on Windows), please at least run `contrib/check-code.py` on
any files you've modified and run `python contrib/check-commit` on any
commits you've made (for example, `python contrib/check-commit
273ce12ad8f1` will report some style violations on a very old commit).
