Fix regression in grease pencil drawing

Drag events finished drawing early.

Workbench: UI for custom studio lights/matcaps

- all known image types are supported
- BpyAPI for studiolights added
- added open user pref operator in shading menu
- possible to add multiple files in a single run

For now refreshing studio lights will free all studiolights and reinit
the whole mechanism. This can be improved by only freeing deleted, reset
updated and add new custom studiolights.

details to show currently only shows the path we perhaps want to add
other information also

Keymap: continued testing/development (search key)

Use Accent/Grave for search, to be more convenient than F-Keys.

This sets F3 back to what it was before.

Redo stats calculation

Now the stat info is saved in the datablock to avoid recalculations and the stats are calculated in one function.

Still pending move the update of the stats to a better place to calculate only when the object change, maybe in depsgraph evaluation.

Improved "Add Region" operator that binds to a selected face map and creates a default bundle.

Fix recently added drag events closing menus

Transform: fix non-3D view editmode assert

Use eval mesh for the scalp consistently, never directly access scalp_object->data.

Keymap: continued testing/development

After testing in the studio and extending the event system for
drag events, we've agreed on adjustments to the new keymap,
see: T55162

- Tab: Edit-mode toggle.
- Tab + Cursor Drag: mode switching pie menu.
- Accent/Grave: for 3D view pie menu.
- F3: Search
- 1..3, Shift-1..3: Edit mesh vertex/edge/face toggle.

Other minor changes were made, however they aren't part of the design.

- Ctrl-Shift-S: Image editor Save-As (was F3)
- Ctrl-Alt-R: Repeat history (was F3)

WM: fix drag events applying after release

GHOST/X11: Xinput/XIM support caused double key-up

All keyboard events were sending double key events (including modifiers)
when xinput was enabled with gnome (causing much confusion!).

I cant test if XIM works,
but this isn't useful to send double events, so disabling for now.
