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.
