Fall cleanup in mozilla.port.mk, in preparation for fx 83

- update nss dep to 3.59, will be required for gecko 84
- drop options to build against systemwide
  cairo/hunspell/libevent/sqlite as those were dropped upstream
  (#1611386 for sqlite, #1432751 for cairo)
- move the dependency for nasm (required for dav1d since 67) from the
  consumers to the module
- move the dependency for rust & llvm from the consumers to the module
  (cbindgen and nodejs are next, but seamonkey doesnt require them yet)
- drop the plumbing for the debug FLAVOR, DEBUG_PACKAGES is the new hotness
- all consumers build against Gtk3, drop MOZILLA_USE_GTK3
