gh-72880: Fix the fontchooser tests on macOS and with wantobjects=0

On macOS the native dialog stores the -font option as a resolved font
description rather than the font name, and with wantobjects=0 Tcl
returns strings instead of integers.  Compare the actual font
attributes and coerce the size to an integer.
