lawnjelly 0a350845d5 BVH - fix stale current_tree in deactivate function
Changes passing of current_tree from a member variable to a function argument, making bugs due to stale state less likely.

Fix a bug in deactivate where current_tree variable was stale. This may have resulted in visual anomalies.

Style: Enforce braces around if blocks and loops
Using clang-tidy's `readability-braces-around-statements`.

PouleyKetchoupp 0dacc681b6 Fixed unnecessary bvh tree updates when calling set_pairable
Dynamic BVH doesn't update the tree anymore when calling set_pairable
with no parameter change.

Also modified Godot Physics broadphase to create objects directly with
pairable (static) set correctly to make use of this optimization for the
BVH broadphase.

Note: Octree broadphase doesn't use this optimization because it forces
an update on move, so passing the proper AABB and static parameters on
creation would cause the tree to update twice.

PouleyKetchoupp d8f681029f Support for Dynamic BVH as 2D Physics broadphase
List of changes:
- Modified bvh class to handle 2D and 3D as a template
- Changes in Rect2, Vector2, Vector3 interface to uniformize template
calls
- New option in Project Settings to enable BVH for 2D Physics (enabled
by default like in 3D)

lawnjelly 00bd087d82 BVH add support for visibility (activation)
A major feature lacking in the octree was proper support for setting visibility / activation. This meant that invisible objects were still causing lots of processing in the tree unnecessarily.

This PR adds proper support for activation, items are temporarily removed from the tree and collision detection when inactive.

lawnjelly a241aeb289 Fix BVH set_pairable and masks.
Calling set_pairable now will update collisions (rather than waiting for the next item_move).

Mask behaviour used for pairing now (hopefully) matches octree.

lawnjelly 7b33050b3d BVH - fix physics expecting plus one based IDs.
Godot physics relies on ID zero being invalid, whereas BVH 0 is a valid ID.

lawnjelly 690e07b509 Dynamic BVH for rendering and godot physics
Complete rewrite of spatial partitioning using a bounding volume hierarchy rather than octree.

Switchable in project settings between using octree or BVH for rendering and physics.
