g_option_context_parse_strv: use UTF-8 on Windows

Browse Source 
Add another difference to the freshly-added g_option_context_parse_strv:
now, on Windows, its arguments on to be in UTF-8 instead of the argv[]
encoding (from the system codepage).

The documentation teases g_win32_get_command_line() which is a new
GLib-filename-encoding-based function that will be added in a following
commit.
