Remove caching of whether any of the children accept focus in wxControlContainer as it can change at any moment under Mac, due to full keyboard access being turned on and off (which can be done using Ctrl-F7, i.e. easily, and so this might be something users actually do and not just a theoretical edge case). This also incidentally fixes caching of the wrong focusability state during window initialization, when its children are not yet shown, as [NSView canBecomeKeyView:] used for AcceptsFocusFromKeyboard() implementation under Mac, apparently always returns false for hidden windows. The behaviour under the other platforms should remain the same, but AcceptsFocus() is slower now as it always has to query children instead of being able to avoid doing it when we know that none of them accepts focus anyhow. OTOH this only happens to the windows that don't accept focus themselves and, at least at some moment, don't have any children accepting focus neither, which should be quite rare and optimizing this case doesn't seem to be worth the extra code complexity due to extra preprocessor platform checks. Closes #18089.
About
wxWidgets is a free and open source cross-platform C++ framework for writing advanced GUI applications using native controls.
wxWidgets allows you to write native-looking GUI applications for all the major desktop platforms and also helps with abstracting the differences in the non-GUI aspects between them. It is free for the use in both open source and commercial applications, comes with the full, easy to read and modify, source and extensive documentation and a collection of more than a hundred examples. You can learn more about wxWidgets at https://www.wxwidgets.org/ and read its documentation online at https://docs.wxwidgets.org/

Licence
wxWidgets licence is a modified version of LGPL explicitly allowing not distributing the sources of an application using the library even in the case of static linking.
Building
For building the library, please see platform-specific documentation under
docs/<port>
directory, e.g. here are the instructions for
wxGTK, wxMSW and
wxOSX.
If you're building the sources checked out from Git, and not from a released version, please see these additional Git-specific notes.
