[PATCH 3/3] MdeModulePkg/TerminalDxe: Handle more keys with TtyTerm

["Brian J. Johnson" <bjohnson@sgi.com>]

The TtyTerm terminal driver is missing support for sequences produced
by the page up, page down, insert, home, and end keys in some terimnal
emulators.  Add them.

Tested under Ubuntu 16.04 using xterm 322-1ubuntu1, GNOME terminal
3.18.3-1ubuntu1, and XFCE terminal 0.6.3-2ubuntu1.
