PS4 target recognizes the #pragma comment() syntax as in -fms-extensions, but
only handles the case of #pragma comment(lib). This patch adds a warning if any
other arguments are encountered.
This patch also refactors the code in ParsePragma.cpp a little bit to make it
more obvious that some codes are being shared between -fms-extensions and PS4.

For #pragma comment(linker, ...) MSVC expects the comment string to be quoted, but for #pragma comment(lib, ...) the compiler itself quotes the library name.
Since this distinction disappears by the time the directive reaches the backend, move quoting for the "lib" version to the frontend.
