RTA: Add Qt desktop CLI install tests using component alias names

As part of Qt release testing process, IFW command-line installations with alias names should be tested in RTA.

It might not be feasible to test every combination of aliases, but tests should cover all 3 desktop platforms. For example, common installations such as qt-essentials or qt-full could be chosen to be tested. Alias package name syntax and intended content can be found in the CLI documentation link at the end.

Note: Installer version 4.8.0 or higher must be used for testing in order for aliases to show up.
