Fix T63921: Unable to use confirm on release for keyboard shortcuts

The first issue was that we were still working around a Xorg bug that
has been solved since a very long time:

https://bugs.freedesktop.org/show_bug.cgi?id=22515

The second issue was that the global "confirm on release for mouse
clicks" was used for keyboard shortcuts as well.

Cleanup: remove unused boost code

Fix T67999: calling obj.data.materials.clear() crashes Blender

The `BKE_material_clear_id()` didn't call `test_all_objects_materials()`,
which caused the object and mesh material slot count to go out of sync.

Refactor access to dependency graph

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 T67902: Crash when undo a loop cut

Have CMake be more strict when optional x11 libraries are missing but enabled

Previously cmake would silently disable features that depended on
certain x11 libraries if they were not found. Now we instead error out
and inform the user that these are missing but optional.

Fix T68001: Rotating vertices on the UV map by a fixed number immediately crashes Blender.

Spaghetti Transform code can use same code for different kind of data.
The 'stepped rotation' process is actually only useful/doable in a few
cases (when we do have some real place to store rotation value, and we
are using Eulers).

Fix T66031: Text Material Change broken.

font_to_curve code was not handling properly the case where it has nop

then, not reset mat indices of chars to default 0 value.

Fix Visual Studio compatibility in writeffmpeg.c

This fixes an incompatibility with Visual Studio 2019 introduced in
631d5026c7bb34320c5d9b60afa5bc44b40fc5e4. It is likely caused by using
`# ifdef` inside the use of the `ELEM()` macro.

Animation: Remove depsgraph argument from a lot of API

Use explicit boolean flag to indicate whether flush to original data
is needed or not. Makes it possible to avoid confusion on whether an
evaluated or any depsgraph can be passed to the API.

Allows to remove depsgraph from bAnimContext as well.

Animation: Remove depsgraph argument from direct keyframing

It was used to access evaluated object and pose and was done prior
to implementation of flushing values back to original data for an
active dependency graph.

Removing the argument allows to simplify API and solve issues with
accessing missing dependency graph on redo.

Fix: Cycles reporting incorrect number of samples in viewport render
