[console] Avoid overlap between remapping flags and character values
The keyboard remapping flags currently occupy bits 8 and upwards of
the to-be-mapped character value. This overlaps the range used for
special keys (KEY_MIN and upwards) and also overlaps the valid Unicode
character range.
No conflict is created by this overlap, since by design only ASCII
character values (as generated by an ASCII-only keyboard driver) are
subject to remapping, and so the to-be-remapped character values exist
in a conceptually separate namespace from either special keys or
non-ASCII Unicode characters. However, the overlap is potentially
confusing for readers of the code.
Minimise cognitive load by using bits 24 and upwards for the keyboard
remapping flags.
