[google_fonts] Make a map keyed on FontWeight non-const (#10058)

jason-simmons · web-flow · commit 651c5654beb6 · 2025-09-24T18:32:53.000Z
A proposed engine PR will allow construction of arbitrary FontWeight instances and thus needs to overload the FontWeight equality operator (see flutter/flutter#175771) With that change it will no longer be possible to use FontWeight as the key in a const map.
