x86/mm: Refactor __set_clr_pte_enc()
Refactor __set_clr_pte_enc() and add two new helper functions to
set/clear PTE C-bit from early SEV/SNP initialization code and later
during shutdown/kexec especially when all CPUs are stopped and
interrupts are disabled and set_memory_xx() interfaces can't be used.
