update spirv-headers and fix handling of gl_HitTEXT (#2471)

Browse source 
* update spirv-headers and fix handling of gl_HitTEXT

Update spirv-headers known_good to f027d53ded7e230e008d37c8b47ede7cd308e19d
and update SPIRV/spirv.hpp to copy from that version as well.

In GLSL gl_HitTNV/gl_HitTEXT is defined as an alias of gl_RayTmaxNV/gl_RayTmaxEXT
SPV_NV_ray_tracing has a dedicated HitTNV which gl_HitTNV maps to.
For SPV_KHR_ray_tracing, gl_HitTEXT gets mapped to a RayTmaxKHR decoraged variable
to simplify the SPIRV consumer.
This change fixes the mapping for the GL_EXT_ray_tracing extension, and updates
the test results to match.

* update MissNV shader test to not use ObjectRay builtins

They shouldn't existing in the miss stage because there is no object intersected
