A few smaller cleanups to the pose mode Select Mirror operator. - Don't store flags in a `void *` on the pose channel, but just use a map to store the pre-mirroring selection flags. - Instead of checking the `extend` flag for every bone, use two functions to either add to the selection or set the selection, and use the 'extend' flag to choose between those once. - Flip some conditions and use `continue` to reduce cognitive complexity. No functional changes. Pull Request: https://projects.blender.org/blender/blender/pulls/136836
