This is a follow-up to #123998 which fixed autokeying on objects when the "Only Insert Needed" user preference was enabled. This fixes an essentially identical bug for auto-keying bones, but *also* fixes a different-but-related bug unique to bone keying. In the first bug the location channel would erroneously not get keyed sometimes when the "Only Insert Needed" user preference was enabled. This fixes that by passing in whether more than one bone is being keyed or not, and using that to accurately determine if location actually needs to be keyed. In the second bug, the location channel would erroneously not get keyed when "Auto IK" was used to transform bones. This fixes that by just being over-conservative. This unforunately leads to more bones getting their location channel keyed than needed when Auto IK is used, but this is better than *failing* to key needed channels, which was the previous behavior. I left a comment explaining the situation, along with a TODO to address this in a more satisfying way in the future. Pull Request: https://projects.blender.org/blender/blender/pulls/124054
