Construct broker app link redirect URI based on broker pkg name + move under /androidbroker path

[shahzaibj]

This basically does a couple of changes:

• 1st: Received feedback from eSTS folks to move app links under androidbroker/ path as opposed to the root of the eSTS domain.
• 2nd: for each broker app specific app link, we were using a friendly identifier at the end such as /authenticator to denote authapp and /ltw to denote ltw. I've moved away from these custom friendly names and decided to just put the pkg name into the path. This allows us to declare an intent filter for it directly in our broker's intent filter as opposed to asking partner teams to put an intent filter in their manifest.

• Update the class documentation to indicate that the app link redirect URI is now generated dynamically via getAppLinkRedirectUri(), as the previous appLinkRedirectUri parameter has been removed.

                      private val nickName: String?) {

common/src/main/java/com/microsoft/identity/common/adal/internal/AuthenticationConstants.java:1489

• Consider extending the documentation for the newly introduced constants (scheme, host, and path prefix) to clarify how they should be combined to construct the complete app link redirect URI.

        public static final String BROKER_APP_LINK_REDIRECT_URL_SCHEME = "https";

Consider using a URI builder or equivalent mechanism to handle URL encoding for the packageName to ensure the generated URI is valid in all cases.
