ac: add load_tess_level() to the abi
Fixes the following piglit tests in radeonsi:
vs-tcs-tes-tessinner-tessouter-inputs-quads.shader_test
vs-tcs-tes-tessinner-tessouter-inputs-tris.shader_test
vs-tes-tessinner-tessouter-inputs-quads.shader_test
vs-tes-tessinner-tessouter-inputs-tris.shader_test
v2: make use of si_shader_io_get_unique_index_patch()
via the helper in the previous patch rather than
shader_io_get_unique_index()
