Added read-only attribute ecefToUsdTransform to CesiumGeoreferencePrim. Previously this was stored in /CesiumSession which has since been removed (and this PR scrubs it out of the code base)
Fixed crash when updating globe anchor when georeferencing is disabled.

@r-veenstra this PR includes USD schema changes, so if you're doing the June release make sure to update the cesium.usd.plugins version number

This looks good. I confirmed the matrix was valid by creating an earth sized sphere and applying the transform. It lines up with the georeferenced globe.
