Synthesizing CUDA tests (#1183)

* When using setUniform clamp the amount of data written to the buffer size.

* CUDA implement StructuredBuffer/ByteAddressBuffer as pointer/count as is on CPU.
Allow bounds check to zero index.
Update docs.

* Synthesize tests.

* Fix bug in CUDA output.

* Fixing more tests to run on CUDA.

* Added BaseType for layout of Vector and Matrix - as they are held as int32_t vector array types.

* Enable unbound array support on CUDA.

* Added unsized array support for CUDA documentation.
