Currently the islands are created depending only on the visible UVs.
This can be confusing because compared to Edit Meshes, islands are created based on the selected elements.
T68284 shows a case where this confusion is observed.

multi-object-editing contains an empty mesh
Since BM_uv_vert_map_create would return NULL for an empty mesh, code
would then return from uv_select_linked_multi [where it should just skip
and continue instead...]

Caused by rBeead6a604602.
Above commit didnt account for different element types being tagged (face
select mode tagged faces, others tagged loops) and always flushed from
loops.
Now restore to flush from faces if we are in face select mode.

Was caused by DRW_mesh_batch_cache_get_edituv_faces_stretch_area called
after DRW_mesh_batch_cache_create_requested. So it was created on the wrong
object/mesh.

When the result isn't used, prefer post increment/decrement
(already used nearly everywhere in Blender).

Support for UV Stretching overlay during multi object editing. The
VBO now holds the ratios per fase. In the shader these ratios will
be compared against the global ratios. The global rations are created
from all selected objects.
The current implementation does not fit well with the draw module. The
plan is to move the drawing of other spaces towards the draw manager what
leads to a better fit. Currently the details on this solution is unclear
but this requirement will become an attentionpoint in the future design.

For clarity sake, the batch cache now uses exclusively per Loop attributes.
While this is a bit of a waste of VRAM (for the few case where per vert
attribs are enough) it reduces the complexity and amount of overall VBO
to update in general situations.
This patch also makes the VertexBuffers filling multithreaded. This make
the update of dense meshes a bit faster. The main bottleneck is the
IndexBuffers update which cannot be multithreaded efficiently (have to
increment a counter and/or do a final sorting pass).
We introduce the concept of "extract" functions/step.
All extract functions are executed in one thread each and if possible,
using multiple thread for looping over all elements.

New operator to select overlapping UV's,
from all visible edit-mesh UV's.

This change ensures that operators which needs access to evaluated data
first makes sure there is a dependency graph.
Other accesses to the dependency graph made it more explicit about
whether they just need a valid dependency graph pointer or whether they
expect the graph to be already evaluated.
This replaces OPTYPE_USE_EVAL_DATA which is now removed.
Some general rules about usage of accessors:
- Drawing is expected to happen from a fully evaluated dependency graph.
There is now a function to access it, which will in the future control
that dependency graph is actually evaluated.
This check is not yet done because there are some things to be taken
care about first: for example, post-update hooks might leave scene in
a state where something is still tagged for update.
- All operators which needs to access evaluated state must use
CTX_data_ensure_evaluated_depsgraph().
This function replaces OPTYPE_USE_EVAL_DATA.
The call is generally to be done in the very beginning of the
operator, prior other logic (unless this is some comprehensive
operator which might or might not need access to an evaluated state).
This call is never to be used from a loop.
If some utility function requires evaluated state of dependency graph
the graph is to be passed as an explicit argument. This way it is
clear that no evaluation happens in a loop or something like this.
- All cases which needs to know dependency graph pointer, but which
doesn't want to actually evaluate it can use old-style function
CTX_data_depsgraph_pointer(), assuming that underlying code will
ensure dependency graph is evaluated prior to accessing it.
- The new functions are replacing OPTYPE_USE_EVAL_DATA, so now it is
explicit and local about where dependency graph is being ensured.
This commit also contains some fixes of wrong usage of evaluation
functions on original objects. Ideally should be split out, but in
reality with all the APIs being renamed is quite tricky.
Fixes T67454: Blender crash on rapid undo and select
Speculation here is that sometimes undo and selection operators are
sometimes handled in the same event loop iteration, which leaves
non-evaluated dependency graph.
Fixes T67973: Crash on Fix Deforms operator
Fixes T67902: Crash when undo a loop cut

CDData checking on file load was not taking into account deprecated
CD_MTEXPOLY datatype, which unfortunately shows same weird glitch as
CD_PAINT_MASK and CD_FACEMAP ones...
Note that it was annoying (due to amount of warnings in console), but
totally harmless, since that data type is just deleted anyway.
This commit also generally cleans up the CD_MTEXPOLY deprecation code, we
have a system to handle that, let's use it, instead of defining local
static values to replace it...

The dash_factor wasn't being set in many places, having the graph editor
open for eg, caused box-select in the 3D view not to show dashes.

The rotation matrix included the global object offset too. Now we only
take into account the actual offset that what sent to the function.

Use depth buffer to order the uv edges correctly to always draw selected
edges on top.
We still use the double drawing workaround for points to keep the smooth
antialiased display.

Cheap tip: anything that is not "Camel Case" and/or that is more than
a few words long should use `TIP_` translation, not `IFACE_` one.

In 2.7x UV sculpt was a kind of sub-mode
(a toggle with it's own key-map & drawing code).
Move this to an operator that uses the tool-system,
this simplifies internal logic, especially brush selection
which now matches sculpt and other paint modes.
- Remove toggle used to enable uv sculpt.
- Expose the brush, which was already used but there was no way to
select different brushes.
- Make UV sculpt use paint paint tool slots
(using brushes how all other paint mode currently do).
- Move UV Sculpt keymap to the tools keymap.
- Remove Q to toggle UV sculpt mode,
S/P/G keys to switch tools.

- Move painting brush panels into the image side-bar.
- Add active tool panel to the image side-bar.

No functional change, this adds LIB definition and args to cmake files.
Without this it's difficult to migrate away from 'BLENDER_SORTED_LIBS'
since there are many platforms/configurations that could break when
changing linking order.
Manually add and enable WITHOUT_SORTED_LIBS to try building
without sorted libs (currently fails since all variables are empty).
This check will eventually be removed.
