Michael Brown bc5c612f75 [console] Include mappings for AltGr-Shift-<key>
The BIOS console's interpretation of LShift+RShift as equivalent to
AltGr requires the shifted ASCII characters to be present in the AltGr
mapping table, to allow AltGr-Shift-<key> to be interpreted in the
same way as AltGr-<key>.

For keyboard layouts that have different ASCII characters for
AltGr-<key> and AltGr-Shift-<key>, this will potentially leave the
character for AltGr-<key> inaccessible via the BIOS console if the
BIOS requires the use of the LShift+RShift workaround.  This
theoretically affects the numeric keys in the Lithuanian ("lt")
keyboard layout (where the numerals are accessed via AltGr-<key> and
punctuation characters via AltGr-Shift-<key>), but the simple
workaround for that keyboard layout is to avoid using AltGr and Shift
entirely since the unmodified numeric keys are not remapped anyway.
