Fix T71247: Outliner pose toggle looses bone selection

The outliner didn't account for weight-paint + pose-mode,
making it consider all pose bones unselected.
When syncing selection, bones were unselected.

This adds a context argument to passed to drawing functions since
finding the weight-paint pose-object in the drawing loop isn't efficient.

No functional change.

Fix python error when trying to delete presets

In some cases the default data paths for blender does not exist.
For example on windows when using the portable install.

This would lead to errors when trying to lookup default paths in
is_path_builtin. Now we handle cases like this gracefully.

UI: Disk to Disc Spelling Change

Identifiers for icons representing optical drives should use 'disc', not 'disk'.

Fix T70725: Frame Symmetry Stroke

Frame Selected centers around the last valid stroke.
When Symmetry is enabled the last mirrored `location` was added to the
`average_stroke_accum` in stead of the original stroke location.

This patch will add the `true_location` to the `average_stroke_accum`.
This contains the original stroke location.

Issue happened in Vertex and Weight paint.

Fix inability to toggle pose-mode without sync-selection

- There was no way to select some kinds of data without activating them.
- Pose mode could not be activated at all.

No change to behavior with sync-selection enabled.

Transform: Add option to exclude back facing geometry from snapping

Add new `Backface Culling` option to the snapping properties.
This option has nothing to do with the view3d display or the
workbench `Backface Culling` option.

Limitation:
- In edit mode, this option only affects snap to faces.
