Rename USDReaderStage::handle_prim().

Renamed to USDReaderStage::collect_readers(), as
it's more descriptive.

Added USDStageReader::handle_prim() function.

Per suggestion by Sybren in his review, moved code from
the static _handlePrim() function to a USDStageReader private
member function. This helps simplify the code as the new
function requires fewer argumants. Also performed minor
cleanup of the function implementation.

USD Import: fixed typo in comment.

USD Import: removed unused ImportSettings member.

ImportSettings::vel_scale was unused and has bee removed.

Enable UMM addon by default.

Added logic to enable the omni addon by default on
startup and when initially setting user preferences.
This appears to be working, but is probably not the
officially sanctioned approach to set defaults, so
this must be investigated further.

Now iterating only over the world shader nodes that are
connected to the world output node, to avoid processing
disconnected nodes in the world node tree. Now also
processing the vector multiplication node to assign
the dome light color.

USD export: fix dome light rotation.

Now setting all rotations components and setting
the rotation order to account for conversion between
extrinsic and intrinsic conventions.

USD dome light export improvements.

Moved code for exporting the environment dome light to
a new world_material_to_dome_light() function. This
logic now includes support for exporting the environment
texture and for using a relative path for this asset.
Also added logic to export the dome light properties
using a naming scheme backward compatible with USD
versions older than 21.
