GLSL: Support both SPV_KHR_ray_tracing and NV_ray_tracing.

Fairly minor differences, so can keep them side by side without too much
effort. NV support is effectively deprecated now however.

- Add OpConvertUToAccelerationStructureKHR
- Ignore/Terminate ray is now a terminator in KHR, but a call in NV.
- Fix some bugs with reportIntersection.
