efi_selftest: Add international characters test
UEFI relies entirely on unicode output, which actual fonts displayed on
the screen might not be ready for.
Add a test displaying some international characters, to reveal missing
glyphs, especially in our builtin fonts.
This would be needed to be manually checked on the screen for
correctness.
