Apply system animation scale to parts of Tachiyomi that don't respect it by default (#5794)

* Add initial code for scaling animations, apply scale to reader nav overlay

* Rename extension function, apply system animator scale to ActionToolbar

* Apply system animator scale to expanding manga cover animation

* Apply system animator scale to image crossfade (also disables animated covers when browsing)

* Add documentation, make MotionScene Transition comment a bit more clear

* Disable animated covers in MangaInfoHeaderAdapter if animator duration scale is 0

* Disable animated covers in Library if animator duration scale is 0

* Convert loadAny listener to extension function

(cherry picked from commit df683375b1d7a15c03d315e85d4a0327b49f8ceb)
