  Execute all unit test cases in all unit test suites added to a Framework.

  Once a unit test framework is initialized and all unit test suites and unit

  @param[in]  FrameworkHandle  A handle to the current running framework that

  @retval  EFI_SUCCESS            All test cases were dispatched.
