ui/console-vc: add UTF-8 input decoding with CP437 rendering The text console receives bytes that may be UTF-8 encoded (e.g. from a guest running a modern distro), but currently treats each byte as a raw character index into the VGA/CP437 font, producing garbled output for any multi-byte sequence. Add a UTF-8 decoder using Bjoern Hoehrmann's DFA. The DFA inherently rejects overlong encodings, surrogates, and codepoints above U+10FFFF. Completed codepoints are then mapped to CP437, unmappable characters are displayed as '?'. Note that QEMU has a "buffered" utf8 decoder in util/unicode.c, but it is not a good fit for byte-per-byte decoding. Reviewed-by: Daniel P.
