Subject: [PATCH] Embarcadero,OpenWatcom: Clear unused flags for creating
 shared libraries

Clear `CMAKE_SHARED_LIBRARY_CREATE_<LANG>_FLAGS` since no special
link flags are needed to create a DLL with these toolchains.
Our shared library creation rules do not reference the placeholder,
so this variable was never used.  However, we may soon teach the
generators to look it up directly.
