[119] Make password provider request optional

[lupidan]

Changed

• Adds ShouldSearchInKeychain to AppleAuthQuickLoginArgs with the default value being false IMPORTANT: QuickLogin was, by default, performing a check for Keychain passwords alongside Apple ID credentials. However due to changes (or bugs) on iPadOS 15.0, this has been moved as an optional check. If your app was supporting Keychain password credentials, you might want to enable it when attempting a QuickLogin. Bear in mind however that this behaviour is inconsistent between iOS 15.0, iPadOS 15.0 and tvOS 15.0.

Removed

• Removes default QuickLogin functionality that checked for existing Keychain passwords alongside Apple ID credentials. It´s now an optional functionality, configurable with a new argument in AppleAuthQuickLoginArgs

This won´t work... It will trigger a normal sign in flow with apple, in which no scopes were ever requested.
