Move the selection flag for pose bones, from the (edit)bone to the pose bone. Previously having multiple instances of armatures in pose mode at the same time caused issues because selecting a pose bone on one armature would automatically select it on all instances of it. This is now fixed since the selection state is stored on the pose bone (Object level) Doing so breaks API compatibility with 4.5 since the RNA property on the Bone no longer affects the pose bone. Instead, there is a new property on the pose bone for that. Due to this change, some runtime flags for the transform system also had to be moved to the pose bone. This is due to the fact that these flags are used by the transform system to pass information between functions. If we keep the flag at the bone level, this wouldn't work with armature instances.
