This function prints a formatted Unicode string to the graphics console device

If the EFI_HII_FONT_PROTOCOL is not present in the handle database, then no
string is printed, and 0 is returned.
@param PointX An X coordinate to print the string.
@param PointY A Y coordinate to print the string.
@param Foreground The foreground color of the string being printed. This is
an optional parameter that may be NULL. If it is NULL,
then the foreground color of the current ConOut device

an optional parameter that may be NULL. If it is NULL,
