ShellPkg: Fixes for shell application launch, argument handling, and version output:

- Fixes shell application launch version output to match ‘ver’ command, as specified by the UEFI Shell spec.
- Adds PcdShellSupplier for <shell-supplier-specific-data> line of version output.  Defaulted to “EDK II”.
- Display only 1 startup.nsh countdown line per second instead of 10 per second.
- Fix issue where command line is just 1 or more “ “ characters and displayed garbage.
- Fix for @echo –off and @echo –on to not restore echo state
