[PDE-198] Add custom code for ComponentToken in supportsInterface (#117)

* add componenttoken interface and script to calculate interfaceid

* add BoringVaultAdapter interface, change interfaceId calculation

* double check interfaceIds

* formatting and fixes boringvaultadapter

* delete helper scripts
