Some quick fixes to reflection API to try to help Falcor
Some quick fixes to reflection API to try to help Falcor

- Expand most queries that handle `TextureType` to handle `TextureTypeBase`, in hopes that this covers most uses of `image*` types in Vulkan GLSL

- Adopt the quick fix from Falcor to return read-write access for shader-storage-block types. Something more comprehensive is probably needed if people want to do queries on these, since constant buffers should really be included, then.
