Andreas Kling 2871df6f0d Kernel: Stop trying to keep InodeVMObject in sync with disk changes ...

As it turns out, Dr. POSIX doesn't require that post-mmap() changes
to a file are reflected in the memory mappings. So we don't actually
have to care about the file size changing (or the contents.)

IIUC, as long as all the MAP_SHARED mappings that refer to the same
inode are in sync, we're good.

This means that VMObjects don't need resizing capabilities. I'm sure
there are ways we can take advantage of this fact.
