Firestore C++: compile ExecutorLibdispatch in Objective-C++ mode (#1237)

dispatch_queue_t is defined differently in libdispatch depending on
whether the library header is being include from Objective-C (or
Objective-C++) code, or else from C or C++ code. Make sure that all
source files in Firestore that include executor_libdispatch.h are
compiled in the same mode (Objective-C++) to avoid linker errors.
