Add host_memory_backend_pagesize() helper
There are a couple places (one generic, one target specific) where we need
to get the host page size associated with a particular memory backend. I
have some upcoming code which will add another place which wants this. So,
for convenience, add a helper function to calculate this.
host_memory_backend_pagesize() returns the host pagesize for a given
HostMemoryBackend object.
