This function is operating on VMAs and rightly belongs in vma.c, where it

rest of mm.

The _install_special_mapping() function will remain in mmap.c as a wrapper,
since this is used by architecture-specific code.

Doing so allows us to isolate more functions in vma.c for the same reasons.

This forms part of work to allow for tracking MAP_PRIVATE file-backed
mappings by their anonymous virtual page offset, as doing so allows us to
isolate and keep code that interacts with this together.

No functional change intended.
