BLI_edgehash: assert when edges use the same vert

This was removed on the recent upgrade.

GP: Cleanup const variables

Fix error in recent key-item filtering

Grouping flags makes it impossible to exclude only modifiers for eg.

Fixes T59303

Fix force fields not affecting rigid bodies

This fixes part of T58991.
Still need to add proper relations so that point cache is marked as outdated
when effectors are modified.

GP: Missing change of texture format in previous commit

Silence warning (const)

Fix T59125: Outliner does not show view layer count

GP: Create Framebuffer textures only if needed

Now, if there aren't grease pencil objects, the textures and framebuffers are not created. This unload GPU Memory when not using GP.

GP: Changes textures from DEPTH24_STENCIL8 to DEPTH_COMPONENT24

As we are not using stencil info, we don't need this in the texture.

BLI: New Edgehash and EdgeSet implementation

The new data structure uses open addressing instead of chaining to resolve collisions in the hash table.

This new structure was never slower than the old implementation in my tests. Code that first inserts all edges and then iterates through all edges (e.g. to remove duplicates) benefits the most, because the `EdgeHashIterator` becomes a simple for loop over a continuous array.

Armature Edit Mode: improve box/lasso select

Mostly rewrite logic which now matches (de)select picking,
share between both operators.

- Support all selection operations (eSelectOp), fixes T59255.

- Add function that selects using 'BONESEL_*' flags & eSelectOp.
This avoids lasso & box select having to handle selection flushing.

- Fix strange behavior with lasso where selecting a bone in a chain
would only select the tip (from 2.7x).

Cleanup: use doxy grouping for view3d select

Easier to navigate, avoid mixing up functionality across the file.

Cleanup: style

Cleanup: replace ifdef w/ stub

Gizmo: multi-object pose-mode gizmo positioning

Gizmo: use general active center calculation

There are some minor differences in center calculation but I don't think
they're important, if so we can update the code.

- Edit-bone uses head (instead of the middle when both are selected).
- Edit-bone flag for restricting components uses the selection instead
of the active bone.

Cleanup: de-duplicate active item center access

Templates: remove redundant directory init

This is now handled when versioning all startups.

Fix building w/o bullet
