Revert property changes in "[DOCS] AnimationPlayer new props, members/methods"

This partially reverts commits e79456519d
and 2d07fe2920, which introduced API changes
needing more in-depth review at this stage.

Kept the removal of "get_position" binding, redundant with
"get_current_animation_position". Kept docs changes where applicable.
Also removed the obsolete "stop_all" method which does the same as "stop".

Fixes #14602.
