rB87c13ac68c47: UX: Prevent click-through panels and used header area

Summary

Does two main changes:

Handle regions in the order as visible on screen. Practically this just means handling overlapping regions before non-overlapping ones.
Don't handle any other regions after having found one containing the mouse pointer.

Like T92364 suggests, this patch changes the clickable area from this:

To almost exactly this:

The Move Orientation: labels on the left of the 3D View tool header can still be clicked through in this patch, otherwise it seems to match.

Fixes T94016, T91538, T91579, T71899.

636–647	This sanity check can(/should) be a separate patch. It was used in an earlier version but isn't really needed anymore. I'd still like to add it.

641	Just passing through and curious-- is there any particular reason to use `BLI_INLINE` here? I assumed we left that complexity to when it provides a real benefit.

641	Since this is really a debug-only check, the extra function call would be a waste of CPU cycles in release builds. I'd be disappointed if compilers didn't already optimize this out, but yeaaah :) So `BLI_INLINE` is just to enforce that, but no strong feelings about it, we can probably trust compilers to figure this out.

This is great! From my tests in several layouts it seems to work as expected. There might be corner cases though so better get it in before/early bcon3.

Here's a quick video, left side is master, right is this patch:

This seems fine, in some cases the margins seem a bit large (lower part of the toolbar for e.g.) but this can be tweaked separately.

Ran into some issues with asserting when opening new files and pressing keys fast, noted inline.

These should be straightforward to solve, so accepting the patch.

source/blender/windowmanager/intern/wm_event_system.c
643	This is asserting is you press multiple keys at once, it's difficult to redo, pressing `sdf` and `xcv` keys in edit-mesh can sometimes redo it. This can be triggered using the following test: `../lib/tests/ui_simulate/run.py --blender='./blender.bin -d --log "ed.undo.*" --log-level 1 --log-show-basename' --tests "test_undo.view3d_mesh_edit_separate"`
3135	This is crashing on making a new file, checking if `CTX_wm_window(C)` isn't NULL resolves.
