It seems nice if VideoBridge could be used in GMP process. video frame handling could be more efficient.

During looking into ChromiumCDMChild::Allocate(), I found a problem :( ChromiumCDMChild::Allocate() is used for the 2 followings.
- output of decrypt
- output of video decode
There is no way for API to explicitly distinguish between the two. Though it is possible to distinguish by a dirty way. Using video bridge could reduce one video frame copy. But using video bridge could be a risk.
Then for now, it seems better to not use video bridge. It is low risk. Created Bug 1855277 for it.

When video frame copy becomes a bottle neck, we could revisit here.
