Allow graceful degradation of MediaProfile with broken configuration.

Currently, when media profile declares something unsupported / broken /
missing, MediaProfile will crash. This patch will change the behavior
to gracefully degradation instead. b/147701370 is an example IRL. If
vendor declares profile unsupported in AOSP, GSI image will crash
instead of having a non-working or suboptimally working camera.
