events even when wxIDLE_PROCESS_SPECIFIED global idle mode is used.

Closes #15104.

Allow wxMSW AutoHANDLE helper to be used with more kinds of handles.

Make AutoHANDLE a template to allow specifying the invalid handle value, which
is inconsistent across Win32 API and is INVALID_HANDLE_VALUE for most kinds of
handles but 0 for some others, e.g. event object handles.

See #16233.

This will be used instead of raw events in wxMSW code in the upcoming commit.

See #16233.

safer.

Hide tooltip when its associated window is hidden in wxMSW.

Don't leave the tooltip shown on screen if the window it was shown for was
hidden or iconized (without moving the mouse, as that would have dismissed the
tooltip as well).

Closes #16265.
