media: Add ARM secure codecs support

This reworks the existing change for H264 secure playback on ARM to pass
the secure_handle through the picture creation method, and attach it to
the picture rather than passing it through SetStream. This is more
compatible with VP9/AV1 codecs and removes the state tracking in the
accelerator.

In order to avoid having to modify all the windows/mac code as well, we
are doing this through an additional method on the accelerator
interface. We will be able to drop this new method once we switch to the
new flat V4L2 stateless decoder as that won't be tying input buffers to
output surfaces anymore. Then we can just put it in media::CodecPicture
and set that one field in the XXXDecoder and then the accelerator can
use it after that.

BUG=b:248610914
TEST=Secure H264 playback works on geralt, other codecs are under
     development still on the kernel/TEE side
