* Remove unused `merge*()` functions (for production) details: Some functionality moved to test suite * Make sure that only `AccountData` leaf type is exactly used on VertexID(1) * clean up payload type * Provide dedicated functions for merging accounts and storage trees why: Storage trees are always linked to an account, so there is no need for an application to fiddle about (e.e. creating, re-cycling) with storage tree vertex IDs. * CoreDb: Disable tracer functionality why: Must be updated to accommodate new/changed `Aristo` functions. * CoreDb: Use new `mergeXXX()` functions why: Makes explicit vertex ID management obsolete for creating new storage trees. * Remove `mergePayload()` and other cruft from API, `aristo_merge`, etc. * clean up merge functions details: The merge implementation `mergePayloadImpl()` does not need to be super generic anymore as all the edge cases are covered by the specialised functions `mergeAccountPayload()`, `mergeGenericData()`, and `mergeStorageData()`. * No tracer available at the moment, so disable offending tests
