Compositor: Add vars and methods for easier image looping

These variables and methods should make it easier to loop through buffers elements/pixels. They take into account single element buffers.
Single element buffers can be used for set operations to reduce memory usage.

Usage example: P2078

Cleanup: too small loop variable type

Animation: move Cycle-Aware Keying to the Keying popover.

The Cycle-Aware Keying option was added in 2.8 and is used
to allow keyframing over cyclic F-Curves without disturbing
the cycle (e.g. overwriting an end keyframe updates both ends).

This effect is not limited to auto keyframing and is applied
to any key insertion, but when the popovers were rearranged
it was put in the Auto-Keyframing related one for some reason.

This is misleading, especially since because of that the
option is incorrectly greyed out when auto keyframing is
disabled, so move it to the generic Keyframing popover.
