[TASK] Streamline Build/Scripts/runTests.sh (#264)

This change modifies the `Build/Scripts/runTests.sh`
execution wrapper to be in line with current TYPO3
core implementation.

This contains following tasks:

* Modify `Build/Scripts/runTests.sh`:
    * `-b <container-binary>` switch to determine which
      container binary should be used.
    * Remove the usage of `docker-compose.yml` file and
      usage by replacing container execution call with
      docker or podman binary calls.
    * Include `bash trap` logic for container/network
      cleanup on abort signals.
    * Keep core `xdebug` flag ability, albeit not used
      currently due to not having tests included.
* Remove `-s composerValidate` and `-s composerNormalize`
  from suit execution, because it can directly dispatched
  using the new `-s composer` dispatcher command. This
  reduces adoption of direct commands for the future.
* Refactor suit command execution without docker-compose.
* Remove `Build/testing-docker/docker-compose.yml` due
  to being obsolete now.
* Add composer related temporary files to `.gitignore`
  and `.gitattributes`.
* Add documentation rendering and test rendering to the
  `runTests.sh`.
