Remove useless compiler options (GH-17553)

* `/Fp` provides a path name for procompiled headers[1], but we don't use
  these.
* `/FR` is used to generate .sbr files; these have been important long
  ago for Visual Studio support, but as of Visual Studio 2008 the IDE
  no longer uses .sbr files.
* `/LD` is used to inform the *compiler* that it should build a DLL[3];
  however, we build all DLLs with the *linker*.
