mm/tlbbatch: rename and extend some functions

This patch does some preparation works to extend batched TLB flush to
arm64. Including:
- Extend set_tlb_ubc_flush_pending() and arch_tlbbatch_add_mm()
  to accept an additional argument for address, architectures
  like arm64 may need this for tlbi.
- Rename arch_tlbbatch_add_mm() to arch_tlbbatch_add_pending()
  to match its current function since we don't need to handle
  mm on architectures like arm64 and add_mm is not proper,
  add_pending will make sense to both as on x86 we're pending the
  TLB flush operations while on arm64 we're pending the synchronize
  operations.

This intends no functional changes on x86.
