MemoryManager: Add validate_userspace_string()
A bit crude, should be replaced by a strdup_from_user() helper to avoid touching userspace memory directly.
But it'll do for now.

MemoryManager: Add an unmap_weak_and_free_vm() helper function
This function mirrors unmap_owned_and_free_vm(), but using weak unmapping (does not free the underlying physical memory)

Convert uses of u64 to usize
Not all of them, but if you're measuring a size it's more appropriate to use usize than u64.

Rename MemoryManager::map to map_frames_at
To make it clearer that this API is only intented for mapping contiguous frames of physical memory (for MMIO perhaps?)

Rename physical "pages" to "frames"
AFAIK, this is the proper naming scheme. "Pages" are virtual, and "frames" physical.
