memrange: add 2 new range_entry routines

Two convenience functions are added to operate on a range_entry:
- range_entry_update_tag() - update the entry's tag
- memranges_next_entry() - get the next entry after the one provide

These functions will be used by a follow on patch to the MTRR code
to allow hole punching in WB region when the default MTRR type is
UC.
