Subject: [PATCH] Add render batch utility functions for depth control

Allows existing draw functions to be drawn out of order at different depths while still using batching.

* Add rlGetRenderBatchActive to match rlSetRenderBatchActive
* Add rlGetRenderBatchDepth to get the depth for the active render batch
* Add rlSetRenderBatchDepth to set the depth for the active render batch
