Message:

VMM: Introduce VMM_HOST_PAGE_SIZE_DYNAMIC, HOST_PAGE_SIZE_DYNAMIC, and HOST_PAGE_SHIFT_DYNAMIC, bugref:10391

HOST_PAGE_SIZE_DYNAMIC either resolves to HOST_PAGE_SIZE or calls RTSystemGetPageSize() on hosts where
the system page size is not known during build time (linux.arm64 for now).
HOST_PAGE_SHIFT_DYNAMIC is the same for the page shift.

This allows building VMM libraries which are agnostic to the host page size (at the cost of a slightly
larger overhead).

Currently enabled only on linux.arm64
