* shader_recompiler: handle fetch shader address offsets
parse index & offset sgpr from fetch shader and propagate them to vkBindVertexBuffers
* shader_recompiler: fix fetch_shader when offset is not present
* video_core: propagate index/offset SGPRs to vkCmdDraw instead of offsetting the buffer address
* video_core: add vertex_offset to non-indexed draw calls
renamed fetch offset fields
* video_core: Remove hack in rasterizer
* The hack was to skip the first draw as the display buffer had not been created yet and the texture cache couldn't create one itself. With this patch it now can, using the color buffer parameters from registers
* shader_recompiler: Implement attribute loads/stores
* video_core: Add basic vertex, index buffer handling and pipeline caching
* externals: Make xxhash lowercase
