Add support for RWBuffer writes on GLSL/SPIR-V target (#1199)
This appears to have been an oversight in the work that added support for `imageStore` as well as atomics when writing to `RWTexture*` and friends. The HLSL/Slang `RWBuffer` type maps to GLSL as an `imageBuffer`, which is effectively just another case of writable texture image (bonus points to anybody who can explain to me the meaningful distinction between an `imageBuffer` and an `image1D`).
This change copies the handling of subscript access (`operator[]`) from textures over to buffers, and adds a test case to confirm that the new handling works for the simple case of setting a buffer element.
