runtime: provide and use a GO_PPC64X_HAS_FUNCDESC define

Rather than implying that all ppc64 GOARCHs use function descriptors,
provide a define for platforms that make use of function descriptors.
Condition on GO_PPC64X_HAS_FUNCDESC when choosing whether or not
to load the entry address from the first slot of the function
descriptor.

Updates #56001.
