Ruiyu Ni 5563281fa2 ShellPkg/[hex]edit: use SimpleTextInEx to read console
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=682

Edit and HexEdit commands assume that SimpleTxtIn translates
Ctrl+<Alpha-Key> key combinations into Unicode control characters
(0x1-0x1A).

Such translation does not seem to be required by the UEFI spec.
Shell should not rely on implementation specific behavior.
It should instead use SimpleTextInEx to read Ctrl+<Alpha-Key> key
combinations.

The patch changes edit and hexedit to only consumes SimpleTextInEx
so that the implementation specific behavior dependency is removed.
