LibOverride: Add Pointer properties to 'overridable by default'.

There is in fact no reason not to do so, RNA pointers are either to
other IDs (which is properly handled by default diffing code), or to
sub-structures that should almost always be diffed as well.

Exceptions (like backward ID pointers or strictly runtime caches and
data) are to be handled with proper 'no comparison' flag in any case.

LibOverride: cleanup Collection case.

This should not give any real difference, those were already
overridable.

Disable gravity in Draw Face Sets brush

Applying gravity to this brush does not make much sense and undo/redo
won't work correctly as it uses a different undo type.

Fix Sharpen mesh filter in Multires

Instead of accumulating displacement for each vertex into the neighbors, accumulate the opposite displacement from each neighbor into the vertex. I think this is the same and it does not produce artifacts in Multires.
