Copy email not work inside Teams Tab App when using Person Card component

[SLdragon]

Teams Tab App do not support Clipboard related js API (see this issue), when I clicked copy button in Person Card component, you will see error messages in console:

Uncaught (in promise) DOMException: The Clipboard API has been blocked because of a 
permissions policy applied to the current document

In my opinion, I think we can add a property to determine whether to show copy button in Person Card or if we detect that current environment do not support clipboard API, we can hide copy button.
