chore: add supported-configurations v2

[BridgeAR]

This adds the supported-configurations.json to php. That file is auto generated from configuration.h. As long as they are in sync, things will work easily. The validation step verifies in the CI if the file got updated or not and would fail, if a change was added without committing.

The one pipeline CI checks are added as well to make sure new configurations are added to the central repository before the PR that adds the config lands.
