This fixes a bug in the protobuf schema registry functionality. Before
this fix one would get a badarith error if one tried to assign a float
value to an uint64 field. However, this commit fixes this by upgrading
gpb so we instead will get a gpb_type_error which is what we want.

- Moves `lib-ee/emqx_ee_schema_registry` to `apps/emqx_schema_registry`.
- Removes the `_ee_` segment from module names.
- Exceptions are the table names which are kept to avoid backwards incompatibilities.
