Fix handling of RT accelerations structures for non-RT stages (#1753)

* Fix handling of RT accelerations structures for non-RT stages

The recent change that added support for the `GL_EXT_ray_query` extension made is so that a shader that declares a `RaytracingAccelerationStructure` as an input to a non-RT shader stage but then never *uses* it wouldn't enable any RT extension, resulting in a compilation failure in glslang.

This change reverts that behavior so that such shaders enable `GL_EXT_ray_tracing`, since that is the older of the two RT extensions that introduce `accelerationStructureEXT`. It is possible that we will need to revisit this decision based on which of the two extensions ends up being more broadly supported, but I think that right now it is fair to say that there exist drivers that support `GL_EXT_ray_tracing` but not `GL_EXT_ray_query`, so the former is the better default.

* fixup: failing test
