[fenix] For https://github.com/mozilla-mobile/fenix/issues/18877 - Support updated PromptRequest AC APIs (https://github.com/mozilla-mobile/fenix/pull/19767)

* For https://github.com/mozilla-mobile/fenix/issues/18877 - Support updated PromptRequest AC APIs

This issue stemming from a race condition is fully resolved in AC by adding
support for having multiple prompts at a time.
Fenix needs just a small change to support the AC refactoring.

* Update Android Components version to 91.0.20210603145049
