[PATCH rfc v2 01/10] mm: add a generic VMA lock-based page fault handler

The ARCH_SUPPORTS_PER_VMA_LOCK are enabled by more and more architectures, eg, x86, arm64, powerpc and s390, and riscv, those implementation are very similar which results in some duplicated codes, let's add a generic VMA lock-based page fault handler try_to_vma_locked_page_fault() to eliminate the
