Scope GRPC/ODB/OpenVDS/HDF5 build flags to avoid full rebuilds

- Remove unused SOURCE_GROUP_HEADER_FILES from GrpcInterface CMakeLists
- Scope the following defines to the files that need it ENABLE_GRPC, USE_ODB_API , USE_OPENVDS, USE_HDF5 
- RifOdbReader.cpp copied an odb_InstanceRepository by value, which
  fails to compile under MSVC's strict conformance mode due to an
  ambiguous implicit copy constructor in the vendor headers (diamond
  inheritance). Use a reference instead, since it was only ever read
  from.
