refspec: relocate omit_name_by_refspec and related functions

Move the functions `omit_name_by_refspec()`, `refspec_match()`, and
`match_name_with_pattern()` from `remote.c` to `refspec.c`. These
functions focus on refspec matching, so placing them in `refspec.c`
aligns with the separation of concerns. Keep refspec-related logic in
`refspec.c` and remote-specific logic in `remote.c` for better code
organization.
