[media] Do not use SupportedProfiles for RTCVideoDecoderAdapter.

SupportedProfiles is a VDA feature and should not be used for
MojoVideoDecoder paths. This CL adds a replacement check via
GpuVideoAcceleratorFactories::IsDecoderConfigSupported(), and
deprecates RTCVideoDecoderFactory::GetSupportedFormats().

If RTC wants to add a dependency on
RTCVideoDecoderFactory::GetSupportedFormats() in the future, there
are a number of challenges related to asynchronicity that must be
solved. For example, reporting 'all supported' before the
GpuVideoAcceleratorFactories cache is filled can totally break a
connection in cases where there is no software fallback.
