Cleanup: Animation, move AnimData API to `anim_data.c`/`BKE_anim_data.h`

The `BKE_animsys.h` and `anim_sys.c` files already had a an "AnimData
API" section. The code in that section has now been split off, and
placed into `BKE_anim_data.h` and `anim_data.c`.

All files that used to include `BKE_animsys.h` have been adjusted to
only include the animation headers they need (sometimes none).

No functional changes.
