Add ppc_ieee128_ok target-supports proc

  Add a target_supports entry to check that the __ieee128 keyword
is understood by the target.
Also add a dg-requires check to the existing pr92796 testcase.

    [testsuite]
	* lib/target-supports.exp (check_effective_target_ppc_ieee128_ok): New.
	* gcc.target/powerpc/pr92796.c: Add a require-effective-target
	statement for ppc_ieee128_ok.
