[TASK] Add `composer` dispatcher to `runTests.sh`

This change adds a composer command dispatcher to
`Build/Scripts/runTests.sh` to allow the execution
of any composer command without the hassle to have
a proper composer installed on the host system.

This also helps for onboarding new contributors not
having a proper php and composer ecosystem installed
on the host system.

For example, to raise dependencies following can now
be used:

> Build/Scripts/runTests.sh -s composer -- require --dev \
  typo3/testing-framework:dev-main

Other examples:

> Build/Scripts/runTests.sh -s composer -- dumpautoload
> Build/Scripts/runTests.sh -s composer -- info | grep "symfony"

Resolves: #103045
Releases: main, 12.4, 11.5
