Include the required headers from wx/custombgwin.h.

Make this header self-contained, i.e. safe to include as the first wxWidgets
header being included from the user code.

Closes #16391.

Add --disable-sys-libs configure option.

This allows to disable the use of all system libraries with a single option
instead of having to use --with-{lib{png,jpeg,tiff},regex,zlib,expat}=builtin
or similar.

This is especially useful under OS X where we want to avoid the dependencies
on any locally installed homebrew or similar libraries.
