Add support for rayQueryGetIntersectionTriangleVertexPositionsEXT (#3463)
Add a member function to RayQuery<RAY_FLAG> class
GetIntersectionTriangleVertexPositions to support the GLSL built-int
rayQueryGetIntersectionTriangleVertexPositionsEXT.
Also add new test file under tests/vkray/rayquery-closesthit.slang
to test this functionality.
