shader_recompiler: handle fetch shader address offsets (#538)

Browse source 
* 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
