This allows to declare SRV buffers in the shader tests using `[buffer srv n]` blocks, and passing them to the different backends. Also, 1/2 includes a missing bit required to parse `Buffer<>` types in the HLSL compiler. This is a step towards supporting StructuredBuffer types in further patches. -- v10: vkd3d-shader/hlsl: Parse Buffer types. tests/shader-runner: Change probe directive syntax on shader_test files. tests/shader-runner: Change resource declaration syntax on shader_test files. tests/shader-runner: Support SRV buffers. tests/shader-runner: Separate resource_type into type and dimension. vkd3d-shader/hlsl: Record valid methods in object_methods[]. https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/569
