freedreno/ir3: Passthrough TCS support

Wire up support for the two intrisics to get default tess levels (which
adds new HS driver params) and add a helper to generate a passthrough
TCS for a given VS.  The passthrough TCS is cached in the VS, indexed by
patch_vertices, as the generated TCS is a function of the VS outputs and
the patch_vertices count.
