wifi: rtw89: mcc: add courtesy mechanism conditions to P2P roles

Browse Source 
In one enablement of courtesy mechanism, there is one provider and
one receiver. And, receiver can use the provider's time in a given
period. But, to make P2P NoA protocol work as expected as possible,
GO should be present at the time it doesn't announce absent, and GC
should not use the time when GO announces absent. So, don't enable
courtesy mechanism if provider is GO or receiver is GC.
