[PATCH] diagnostics: Fix compile error for MinGW <7.0

[Torbjörn SVENSSON]

Ok for trunk?

--

The define ENABLE_VIRTUAL_TERMINAL_PROCESSING was introduced in MinGW
7.0

gcc/ChangeLog:

        * gcc/diagnostic-color.cc: Conditionally enable terminal
        processing based on available MinGW version.
        * gcc/pretty-print.cc: Likewise.
