Add test for absence of events from wxSpinCtrlDouble ctor.

Run the same NoEventsInCtor() test as we already had for wxSpinCtrl for
wxSpinCtrlDouble as well.

Unfortunately currently there is no way to reuse the tests between these two
classes, we should refactor these test cases to use a common
SpinCtrlTestCaseBase<T> base class.

See #15375 which fixed the underlying bug.

Don't generate any events from wxSpinCtrl and wxSpinCtrlDouble methods.

After the changes of r53758 wxMSW didn't generate any wxEVT_TEXT events but
this was still the case for the generic version (and hence for
wxSpinCtrlDouble under MSW too) and wasn't documented.

Fix all versions to avoid sending events for programmatic actions, add unit
tests checking this behaviour and document it.

Reflect changes in stc.cpp in stc.cpp.in from which it's generated.

This should have been part of r74596, see #15353.

Use RIAA wrapper for wxSpinCtrl event disabling in wxGTK.

The use of wxSpinCtrlEventDisabler class ensures that we never forget to
reenable the events after disabling them.

Fix a couple of spelling mistakes in the documentation.

Fix column sorting UI in wxDataViewCtrl under wxOSX.

Use -outlineView:didClickTableColumn: delegate method instead of
mouseDownInHeaderOfTableColumn: one to ensure that:

(a) We don't sort the column if it's being dragged/resized (closes #15340).
(b) We sort the column on mouse up, not down (closes #15386).
