Also apply flipping correction when bone's X-axis is aligned with Y.

Attempt at fixing T88281: Pose Library 'flip pose' sometimes flips wrong

When flipping a pose in the pose library, sometimes the resulting pose
can be wrong. This seems to happen when the rest orientation of the bone
has its X-axis straight up/down. In these cases, an extra -1 scale to
the X and Z axes of the resulting matrix seems to fix things.

This is not a final fix, just a commit to a branch so that animators can
get a test build.

Cleanup: typo fix

Add a comma.

No functional changes.

Cleanup: add `const` to local variables and function parameters

Add `const` to some variables that don't need to be mutable.

No functional changes.

Cleanup: reduce amount of conditional code

Use `return;` in `if`-block, making it possible to un-indent the entire
`else` block.

No functional changes.

Cleanup: remove unused `#include`

Remove unused `#include <stdio.h>`.

No functional changes.

Cleanup: `CTX_wm_asset_handle`, move assignment of return param

Move the assignment to return parameter `*r_is_valid` to always be just
above the corresponding `return` statement. This makes it easier to ensure
that it is always set, and to see that it's only set once.

Cleanup: make `struct PoseBackup` an opaque struct

Move `struct PoseBackup` into `pose_backup.c`, making it opaque to users
of the `ED_pose_backup_...()` functions. This produces a slightly nicer
API for the pose backup system.
