Support for gl_HitTriangleVertexPositionsEXT (#3405) (#3442)
* Support for gl_HitTriangleVertexPositionsEXT (#3405)
Adding float3 HitTriangleVertexPositions(uint) to slang stdlib
to support GLSL gl_HitTriangleVertexPositionsEXT builtin variable
under extension of GL_EXT_ray_tracing_position_fetch.
This function support emitting GLSL code and spir-V directly.
* Update the function name
