mm/mmap: Use advanced maple tree API for mmap_region()

Changing mmap_region() to use the maple tree state and the advanced
maple tree interface allows for a lot less tree walking.

This change removes the last caller of munmap_vma_range(), so drop this
unused function.

Add vma_expand() to expand a VMA if possible by doing the necessary
hugepage check, uprobe_munmap of files, dcache flush, modifications then
undoing the detaches, etc.
