spirv/cfg: Make the builder fully capable for both walks
We were only initializing vtn_builder::func for the pre-walk where we
build the CFG. We were only initializing the nir_builder for the later
walk through the instructions even though were were setting b->cursor
for the pre-walk. Let's set both both places so that everything is
consistent. This useful because we handle OpFunctionParameter in the
pre-walk and we're going to need to be able to emit instructions.
