Add missing "Section" key for Apple ISO keyboards.
(Arabic, British English, Dutch, International English, Portuguese, Swiss, Swedish...)
Fix T65532 can't assign some keys on apple keyboards.
There are two types of apple keyboards "US English" (ANSI type) and "International English" (ISO type).
All non-english keyboards are also ISO type.

In the case of the ISO, the tilde/accent-grave key is located to the left of Z key.
To the left of 1 is an additional kVK_ISO_Section key, which is currently set as "unknown".
This patch makes it possible to use this key.
The same can also be done for the kVK_ANSI_KeypadClear key.
