win32: changes to console mode handling

Add the environment variable BB_TERMINAL_MODE as a more general way
of controlling console/terminal mode setting.  The default remains
unchanged:  use virtual terminal mode for output if possible but
fall back to the console API with emulated ANSI escape sequences.

Currently valid settings are:

   0  Force use of console mode
   1  Force use of virtual terminal mode for output
   5  Prefer virtual terminal mode for output, fall back to console

Other values won't do anything useful until code elsewhere has been
updated.

BB_SKIP_ANSI_EMULATION remains available for backwards compatibility.
If both variables are set BB_TERMINAL_MODE takes precedence.
