The SimpleTestOut test cases don't allow SetMode to return
EFI_UNSUPPORTED, which doesn't comply with UEFI spec.

UEFI spec allows EFI_SIMPLE_TEXT_OUT_PROTOCOL.SetMode function to
return EFI_UNSUPPORTED for the condition below:

if the output devices support 80x50, that is defined to be mode 1.
All other text dimensions supported by the device will follow as
modes 2 and above. If an output device supports modes 2 and above,
but does not support 80x50, then querying for mode 1 will return
EFI_UNSUPPORTED.

Therefore, update the test cases to fix this issue.
