Andreas Kling d481ae95b5 Kernel: Defer creation of Region CoW bitmaps until they're needed
Instead of allocating and populating a Copy-on-Write bitmap for each
Region up front, wait until we actually clone the Region for sharing
with another process.

In most cases, we never need any CoW bits and we save ourselves a lot
of kmalloc() memory and time.
