refs: store the main ref store inside the repository struct

This moves the 'main_ref_store', which was a global variable in refs.c
into the repository struct.

This patch does not deal with the parts in the refs subsystem which deal
with the submodules there. A later patch needs to get rid of the submodule
exposure in the refs API, such as 'get_submodule_ref_store(path)'.
