Adds method to set the visibility of the Asset's prims

[Mayankm96]

Description

This MR adds a function to set the visibility of prims corresponding to an Asset. This is useful for randomization of distractors for visual effects.

Note: Currently, this is not implemented for RigidObjectCollection as it seems unclear how to "index" the prims in there.
