arch/Kconfig: remove virtual memory allocator dependency from MM_SHM 

The dependency should be vice versa; the MM_SHM should depend on the
existence of the virtual memory range allocator.

Create a new CONFIG flag CONFIG_ARCH_VMA_MAPPING, which will define that
there is a virtual memory range allocator. Make MM_SHM select that flag
