Fix linker errors in validation suite for WoA

* Cleaned up the ActivationLayerFixture and removed the context
  becuase it was causing compiler errors with clang-cl

* The runtime context is an experimental feature that is only tested
  in the ActivationLayerFixture and not used anywhere else in the
  codebase

* Resolves MLCE-1209
