vga: Change the arguments of vga_write_text to support extended ASCII
VGA defined the extended ASCII set based on CP437, but the function
vga_write_text() accepts a signed char array.
This will cause unnecessary confusion that if we want to print u with
umlaut (code=129 in CP437), we need to explicitly cast it to -127 in
signed char.
Since we still want to leverage the built-in string utilities
which only accepts const char*, we still need to cast it to signed char
while processing, and cast it back to unsigned once we write into the
frame buffer.
