Convert the long line of if() statements to a switch() since this makes better use of the C language.

The whole code is not well suited to parse all of the many different escape sequences that can be sent to convey modifier keys or non-character keys (think of <CTRL><ALT><F12> or <HOME>).
We should move the of logic of efi_cin_read_key_stroke_ex() to a library function which is used both by bootmenu and UEFI and remove duplicate code.
Sorry I am not about to put effort into the EFI code :-)
Also I did create a library to handle keystrokes. See cli_getch.c
