nir: Add intrinsics for lowering UBOs/VBOs on AGX

We'll use formatted loads and some system values to lower UBOs and VBOs to
global memory in NIR, using the AGX-specific format support and addressing
arithmetic to optimize the emitted code.

Add the intrinsics and teach nir_opt_preamble how to move them so we don't
regress UBO pushing.
