Daniel Kulp e3c466eb71 Support wxFileDialog extra controls in sandboxed apps on macOS ...

Extra controls (including the file type filter choice) have been disabled
in sandboxed applications since the 2013-era workaround for #14906: the
native save/open panel runs out of process (Powerbox/NSRemoteView) and
inserting our views into its view hierarchy crashed.

The supported contract is to build the accessory view entirely in-process
and hand the finished NSView to -[NSSavePanel setAccessoryView:]; the
panel then hosts it safely even when remote. Do exactly that: create the
extra control and the filter panel as children of a hidden in-process
host window instead of parenting them to the (possibly remote) panel.

This makes extra controls and file type filters work in sandboxed
applications too. As a safety valve, a system option, which can be set
by the user by setting wx_osx_openfiledialog_disable_extra_controls
environment variable to 1, is provided to restore the old behaviour of
simply ignoring the extra controls.

Closes #26908.
