Add check for Content Share Support

[Aarondorn2]

as requested in #301, it would be very useful to have a browser compatibility check for whether Content Share is supported (possibly in the DefaultBrowserBehavior class). The original issue was closed as mobile browsers were not supported at the time, but they appear to be now.

thanks for all the hard work!

Unfortunately, the method screenShareUnsupported is deprecated as shown in DefaultBrowserBehavior class. For more info on where content share is supported - refer to this doc: https://docs.aws.amazon.com/chime/latest/dg/meetings-sdk.html#mtg-browsers

I think what you're asking for is basically a more updated version of a method like isContentShareSupported, in which case, I'll keep this label this as a feature enhancement.
