Fix issue creating dimensional constraints
During chunk creation, the chunk's dimensional CHECK constraints are created via an "upcall" to PL/pgSQL code. However, creating dimensional constraints in PL/pgSQL code sometimes fails, especially during high-concurrency inserts, because PL/pgSQL code scans metadata using a snapshot that might not see the same metadata as the C code. As a result, chunk creation sometimes fail during constraint creation. To fix this issue, implement dimensional CHECK-constraint creation in C code. Other constraints (FK, PK, etc.) are still created via an upcall, but should probably also be rewritten in C. However, since these constraints don't depend on recently updated metadata, this is left to a future change. Fixes #5456
