The idea is to share a mesh data-block as a result across all objects
which are sharing same original mesh and have no effective modifiers.
This mesh is owned by an original copy-on-written version of object data.
Tricky part is to make sure it is only initialized once, and currently a
silly mutex lock is used. In practice it only locks if the mesh is not
already there.
As an extra bonus, even viewport memory is also lower after this change.

Depsgraph: Only invoke callbacks when there are changes
Only affects when an evaluated dependency graph is requested via
context.
Makes it cheap to call when there are no changes made to the graph
Transform: Ensure depsgraph is evaluated when needed
Fix based on D4455 from Campbell, utilizes some recently
introduced functions and allows to not have any extra checks
in the transform code.

three issues here:
- when curves had multiple nurbs, the active vert is per nurb
[curve_create_edit_data_and_handles() wasnt taking that into account]
- code could go wrong when points where hidden
- upon selection, tag curve ID_RECALC_COPY_ON_WRITE for batch cache

The calculation of the mix color was not using the bottom color when the alpha was lower than 1.0.
Also added clamp code to avoid values outside valid ranges.
When XRay is turned on the mesh analysis did not draw correct. This
change won't draw the mesh analysis overlay when xray is turned on.
In terms of giving the user a visual feedback of this limitation we
render the overlay options inactive.

The previous fix to the spike bug T64582 was not really right.
This fixes that one properly and restores the desired curving
profile in the bug's example.
sidebar UIList
nodesockets were actually drawn, but immediately drawn over by widgets
from the widget draw batch cache.
solution here is to "widgify" nodesocket drawing as well.

Minor changes to recent gizmo click/drag logic 08dff7b40b
Changing the gizmos highlighted part in the invoke_prepare
callback is too error prone since it needs to run
before it's known which operator will execute.
Add back 'drag_part', since it simplifies click-drag use.
While this isn't essential with custom keymaps per gizmo
it avoids having to define a keymap in the case a drag
event needs a different action.
