[PATCH v3 6/7] efi_selftest: Add geometric shapes character selftest

[Janne Grunau via B4 Relay]

From: Janne Grunau <j at jannau.net>

Draw symbols from Unicode's "Geometric shapes" page which translate to
code page 437 code points 1-31. These are used by UEFI applications to
draw user interfaces using EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL.
The output has to be checked manually on the screen for correctness.
