Bitmap: Add a fallible variant of match_region() that does not crash if arguments are out of range
...
continuous-integration/drone/push Build is passing
This lets us call deallocate_memory() with any address and it will not crash.

Bitmap: Add a 'find_and_toggle' method
...
continuous-integration/drone/push Build is passing
Just like find(), but toggles the value when finding it.
Avoids doing this manually in MemoryManager and KernelVM.

Bitmap: Introduce a new method 'find' and use it in MM and KernelVM
...
continuous-integration/drone/push Build is passing
This method looks for the first bit with a value, optionally from a starting index, and returns its index.
This should be (haven't benchmarked) way faster than the manual way,
AKA what MM and KernelVM were doing.
This is due to this method using bit and byte manipulation tricks instead of just calling get() until getting the desired result :)
