KVM: arm64: Extract page table mapping in user_mem_abort()

Extract the code responsible for locking the KVM MMU and mapping the PFN
into the stage-2 page tables into a new helper, kvm_s2_fault_map().

This helper manages the kvm_fault_lock, checks for MMU invalidation
retries, attempts to adjust for transparent huge pages (THP), handles
MTE sanitization if needed, and finally maps or relaxes permissions on
the stage-2 entries.

With this change, the main user_mem_abort() function is now a sequential
dispatcher that delegates to specialized helper functions.
