MdeModulePkg/TerminalDxe: Fix Backspace key for VT-UTF8 terminal type
When QEMU is launched with -nographic, the Backspace key (DEL, 0x7f)
doesn't work in the UEFI Shell because the VT-UTF8 terminal type
interprets DEL as SCAN_DELETE instead of CHAR_BACKSPACE.
Modern terminal emulators (xterm, gnome-terminal, etc.) send DEL (0x7f)
for Backspace and are UTF-8 compatible. This patch updates
TerminalTypeVtUtf8 to interpret DEL as CHAR_BACKSPACE, consistent with
how TerminalTypeTtyTerm already handles it.
This approach preserves VT-UTF8 as the default terminal type (which
supports full Unicode), while fixing the Backspace functionality for
modern terminal environments.
