pretty-print: Don't translate escape sequences to windows console API

Modern versions of windows (after windows 10 v1511) support VT100 escape
sequences, so translation for them is not necessary. The translation also
mangles embedded warning documentation links.

gcc/ChangeLog:
	* pretty-print.cc (mingw_ansi_fputs): Don't translate escape sequences if
	the console has ENABLE_VIRTUAL_TERMINAL_PROCESSING.
