WM: move mousemove out of internal undo function

This causes a feedback loop in 2.8x,
where gizmo redo caused fake mousemove that executed gizmo again.

Move the mousemove into the undo/redo operator.

Workspaces: reference count screens, otherwise they are never freed.

They are not directly accessible in the UI anymore, it's the workspaces
that we always keep until they are manually deleted now.

Gizmo: avoid redundant value2d updates

Gizmo: set header text when editing the value

Gizmo: value2d cancel, snap & precise support

GP: Sample points in both sides for soft eraser

Now the soft eraser use the previous point and not only current and next. This makes the transition smoother.

GP: Improve soft eraser rounded caps

When draw segments the rounded cap must be only visible in some situations.

Tentative fix for T56770: Crash after set language to Simplified Chinese.

That bug probably did not affect 2.7x, only 2.8 with COW copying IDs in
threads... But root of the issue is that underlying boost i18n lib does
not support well multi-threaded access. So simply forbid any translation
from non-main thread. This *may* be an annoying limit at some point, but
doubt it will be any issue currently.

PyDoc: add bpy.app.icons to docs

PyAPI: add API call to get an operators type

Getting the instance leaks memory and was only meant to be used for
generating docs.
