[OPENJPA-2955] Do not remove schema generation keys from the caller's

> **(medium)** `extractSchemaGenObjects` calls `map.remove(key)` on the
> caller-supplied properties map - this mutates user configuration and throws
> UnsupportedOperationException for unmodifiable maps (e.g. `Map.of(...)`
> passed to `createEntityManagerFactory`). Can the Writer/Reader values be
> captured without mutating the input?
