Add support for RaytracingAccelerationStructure type for PTX targets (#1831)
Add support for RaytracingAccelerationStructure type for PTX targets (#1831)

* enabling command line compiler to output PTX with multiple entry points.

* adding some simple optix intrinsics to slang

* Now handling the kIROp_RaytracingAccelerationStructureType for CUDA. Source seems to generate correctly, but accels are always optimized out of resulting PTX due to no trace calls

* fixing unnecessary diff with master

* allowing unhandled untyped buffers to fall through to super::calcTypeName
