Fix spin-gizmo not allowing click events to select vertices

Fix spin-gizmo button tool-tip placement

gizmo_button2d_bounds result wasn't valid when the gizmo was part
of a 3D gizmo group.

Regression in cf6d17a6aa421e0038fc1f8e60e3f1f708887c3e

Cleanup: Rename variables to indicate what is evaluated

`ob` --> `ob_eval`
`me` --> `me_eval`
`em` --> `em_eval`

Fix typo in previous commit

`has_loose_edge` -> `has_loose_vert`

Cleanup: Use utility to init userdata in 'transfrom_snap_object.c'

This deduplicates the code making it easier to edit.

Transform Snap Object: Improve code that detects updates

The previous code had unclear hacks to avoid updating while transforming,
it was also duplicated in two functions causing an inconsistent
initialization of the looptris bvhtree (which could even generate
unpredictable snapping results).

Now, detection update and inicializatiom of common members are contained in
`snap_object_data_mesh_get` and `snap_object_data_editmesh_get`.

Also, the "Hack to avoid updating while transforming" is more evident.

Merge branch 'blender-v2.93-release'

Fix snap mixed with vertices ignored for meshes with vertices only

The logic assumed that there were only 3 basic snapping modes.

Merge branch 'blender-v2.93-release'

Fix compile warning

The order of the two parameters was incorrect.

Cleanup: make format

Cleanup: clang tidy readability-else-after-return

Merge branch 'blender-v2.93-release'

Fix memory leak in the BLI_bitmap created in 'looptri_no_hidden_map_get'

Snap Gizmo Refactor: Implement options for the gizmo behavior

The Snap Gizmo now has options for occlusion, selection filter and edit
geometry.

It will be useful to implement in current tools.

Measure Tool: Snap to Cage Geometry

For Measure tool, it is more useful to snap to what is really visible.

So use the cage instead of the geometry that may be hidden with Bmesh.

Fix recent snap refactor

It is important to check if editmesh eval cage is also bmesh.

Transform Snap Refactor: Use enum for cage snap options

This allows the addition of the `SNAP_GEOM_CAGE` option.
Currently unused.

Merge branch 'blender-v2.93-release'

Fix T86805 Inconsistent results for exact boolean.

The fast triangulator from Blenlib could leave a non-manifold mesh
after removing degenerate triangles. Switched to an exact triangulator.
