vo_gpu: hwdec: remove redundant fields

The testing_only field is not referenced anymore with vaglx removed and
the previous commit dropping all uses.

The ra_hwdec_driver.api field became unused with the previous commit,
but all hwdec interop drivers still initialized it.

Since this touches highly OS-specific code, build regressions are
possible (plus the previous commit might break hw decoding at runtime).
At least hwdec_cuda.c still used the .api field, other than initializing
it.
