* Rename everything related to built-in profile both in code and UI.
* Unified style for [Read-only] and [Default] badges in profile
manager's list model.
* Change --fallback-profile option to --builtin-profile.
* Backward compatibility: yes. If a user happened to name their
profile "Built-in", it would continue to work as normal, and even
load with `--profile "Built-in"` command line flag. It will let them
modify any property including Name; but changing the name back
to "Built-in" shows a warning and reverts the change as usual.
* Remove "This option is a shortcut for" sentence. While it is still
technically possible to pass built-in profile's magic path, this
option is not a shortcut, nor implemented as such.
* Delete extra naming conditions in ProfileManager::changeProfile,
because they could never be triggered anyway, due to pre-flight
checks in EditProfileDialog::isProfileNameValid. Automatic unique
profile names generation has been done even earlier in either
SessionController or ProfileSettings. Just as before, users will
continue experiencing a generic "A profile with the name \"%1\"
already exists." message.
Tests:
* Improve test for uncreatable file name of built-in profile.
* Add backward compatibility test for loading existing profile
named "Built-in" which also references real built-in as its parent.
