refspec: relocate apply_refspecs and related funtions

Move the functions `apply_refspecs()` and `apply_negative_refspecs()`
from `remote.c` to `refspec.c`. These functions focus on applying
refspecs, so centralizing them in `refspec.c` improves code organization
by keeping refspec-related logic in one place.
