Bug 1800882 - Keep includes in AnimationFrameProvider.h down. r=aosmond

This fixes rusttests. Otherwise we include HTMLVideoElement.h from
Document.h, which includes a bunch of media headers, which causes
rusttest failures because
https://searchfox.org/mozilla-central/rev/d353cfa1fbd207e13dc974f30e5f88535a4303ae/dom/media/platforms/EncoderConfig.h#95
hits https://github.com/rust-lang/rust-bindgen/issues/380.

We could hide those types from rust but it seems slightly nicer to keep
Document.h lean, since it's included in a gazillion places.
