radv: fix missing ZRANGE_PRECISION(1) for GFX9+

ZRANGE_PRECISION(1) seems to be the default optimal value, but
it was only set for VI and older chips.

This fixes a rendering issue with Banished through DXVK, and
might fix more than that.

There is still the ZRANGE_PRECISION bug that we need to handle
but that can be fixed later.
