checkout: factor out mark_cache_entry_for_checkout function

Factor out the code that marks a cache entry as matched for checkout
into a separate function.  We are going to introduce a new mode in
'git checkout' in a subsequent commit, that is going to have a
slightly different logic.  This would make this code unnecessarily
complex.

Moving that complexity into separate functions will make the code in
the subsequent step easier to follow.
