USD Import: don't merge instance Xforms.

Fixed bug to disallow merging instance Xforms when instancing
is enabled, because this prevents instance readers from being
created for such Xforms.

USD Import: format fixes.

USD Import: unit conversion scale option.

Added Apply Unit Conversion Scale option to scale
the scene by the USD stage's meters-per-unit value,
which is applied in addition to the value specified
by the Scale option.

Reverting previous commit that removed instancing
functionality.

USD Export: spurious error message.

Calling BLI_dir_create_recursive() with a path that has a
trailing slash generates an error message that the directory
couldn't be created, even though the creation is successful.
The error message appears to be spurious, but I changed the
code to use a path with no trailing slash, to avoid this.

USD export: export UDIM textures.

Extended the texture export function to handle copying
sequnces of tiled images for UDIM textures. Also, split
the texture export code into several functions for
organization and readability.

USD exporter: null guard in create_data_writer().

Guard against dereferencing null data_writer.

USD import: use __func__ for MEM_callocN() names.

hard-coded names with the __func__ macro for MED_callocN()
name arguments, to help ensure names do not become obsolete
in the future.

USD IO: removed unnecessary format change.
