Recognize Intel compiler as MSVC one under Windows in the build options.

The two compilers are binary compatible and by pretending that Intel compiler
is the same as MSVC, we allow using ICC to build applications using DLLs built
with MSVC.

Closes #9437.

(this is a backport of r76425 from trunk).

Revert "Skip mouse button release events in wxGenericTreeCtrl."

This reverts r76093 as it broke label editing in the control.

See #16055, closes #16573.

Don't prevent the other button release handlers from running in wxGTK.

There doesn't seem to be any advantage in doing this, but it can result in
problems see #16055. So just always let the other handlers for this event
execute as well, even if we did process it.

Revert "Skip mouse button release events in wxGenericListCtrl."

This reverts r76825 as it is not necessary any longer, the fix in the previous
commit takes care of this problem more generally.

See #16365.
