radv: add support for mesh/task shader queries on GFX10.3
On GFX10.3, these queries need to be emulated (the shader code already landed), while on GFX11 they are natively supported by the hardware.
GFX11 support will come right after this work.
This pass all dEQP-VK.mesh_shader.ext.query.* except some line tests which are broken with/without queries.
