LibOverride: Add a utils to check if override has been user-edited.

Cycles: Fix assert in tile manager

Was caused by the recent deletion of tile order.
Need to use tile order which is friendly for viewport rendering.

Cycles: Bring progress report back

Is a bit weird mixture of Progress object and a callback.

The idea is that Progress object is used to communicate progress within
the current big tile from PathTrace to owner of the progress object.

The callback is called after that, so that the (in this case) Session
can assemble full status and report it to the interface.

On a positive side the cancel callback becomes unneeded.

USD Import: USDPrimReader uninitialized members.

Fixed bug where several USDPrimReader class member variables
were not being intialized in the constructor. One of the
previously uninitialized variables stores the reference count,
which was causing memory leaks in some cases.

USD Import: UV fixes.

Made the following updates to fix UV import errors:
Added logic to read UVs with Vertex interpolation and
indexed UVs. Fixed incorrect UV winding order for
left-handed orientation.
