Actually, the NPU demos were not making use of the NPU, just the CPU. To enable the NPU usage,
it is required to add the external delegate library 'tflite-vx-delegate'to the system. This is
done by forcing 'tensorflow-lite' to depend on it for the CCMP2 platform, which also requires
'tim-vx' library as a build dependency.
Both the 'tflite-vx-delegate' and 'tim-vx' recipes have been verbatim copied from the ST Beta
branch, using commit with SHA256: 68686850c75061f1c7c4e756a313a41ca810f6ae

Customize the NPU samples provided by ST so they can be executed in our DEY images:
- Add a generic launch script to pre-configure environment variables before launching demos.
- Remove 'weston' user check from demos launch scripts.
- Reduce font size for big screens.
- Set camera resolution to 640x480px and center the image.
- Adapt home folder to 'root' user instead of 'weston'.
- Adapt package group to include the new samples and remove the old ones.
- Fix a couple of errors with models download and include them manually.
- Add a runtime dependency with 'libdrm-tests' as the 'modetest' binary is required.

These examples have a gtk+3 dependency that can't be met on the ccmp13 due to
it being a headless device. Remove these examples from the packagegroups so we
can at least build the rest of the ML packages.
Note that all of ST's ML examples are GUI-based and will not be usable on the
ccmp13, but since the remaining examples don't have an explicit gtk+3
dependency, at least they won't trigger build errors when included in the
image.
