[FEATURE] Add aliases to Backend Routes and Modules

Symfony 5.4 ships with a new feature to add "aliases"
to routes. TYPO3 can now replace legacy and complicated
names for routes or modules with new ones while keeping
backwards-compatibility with old links / references.

See https://symfony.com/blog/new-in-symfony-5-4-route-aliasing
for more details.

Module registration now allows to define "aliases" (array),
same for route registration.

As an example, complicated module name such as "web_WorkspacesWorkspaces"
is renamed to "workspaces_admin" which reflects the current possibilities
for module identifiers much better.

An upgrade wizard migrates the current backend user
and backend group permissions ("userMods" and "groupMods")
to the new logic.
