efi_loader: console: Correctly report modes
Add support for EFI console modes.
Mode 0 is always 80x25 and present by EFI specification.
Mode 1 is always 80x50 and not mandatory.
Mode 2 and above is freely usable.
If the terminal can handle mode 1, we mark it as supported.
If the terminal size is greater than mode 0 and different than mode 1,
we install it as mode 2.
Modes can be switch with cout_set_mode.
Changes in V5:
Correctly detect mode before enabling mode 2.
Changes in V4:
Reset cursor positon on mode switch
Use local variables in console query code
Changes in V3:
Valid mode are 0 to EFIMode-1
Fix style
Changes in V2:
Add mode switch
Report only the modes that we support
