Add to CustomTabsOptions ability to disable opening auth in custom tab

[bennycao]

Changes

Add option in CustomTabsOptions to define a list of browser packages where you do not want to launch the authentication url in custom tab. This adds feature #805 to solve incompatible custom tab browser.

Please describe both what is changing and why this is important. Include:

• create new method for CustomTabOptions builder withDisabledCustomTabsPackages to define list of custom tab packages to disable which assigns to new instance variable disabledCustomTabsPackages
• update CustomTabOptions.toIntent to get preferredPackage which is the preferred browser package calculated by browser picker.
• update CustomTabOptions.toIntent to validate if the preferredPackage is in the disabledCustomTabsPackages list, and if so, just return Intent with action of Intent.ACTION_VIEW only
