I’m debating this change... this is a breaking change for any user that tried to use the generate_tpc API with IMX500_TP_MODEL
Not sure that we want to break every potential user with this, and we can wait with this to the extraction of the IMX500 TPCs to the external repo.

I want to get rid of the model_compression_toolkit/target_platform_capabilities/target_platform level in the hierarchy, there is no need for it anymore since there is only the /targetplatform2framework/ in it.
Is it too complicated for this huge PR or do you think it would be fine to include this here as well?
