ShellPkg: Add support for input with separately reported modifiers

Browse Source 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2510

Some firmwares:
- Report Shift modifier even when they report upper-case unicode letter.
- Report Ctrl modifier with "shifted" UniChar (i.e. X - 'A' + 1).

This change provides support for these firmwares preserving the compatibility
with the previous input handling.
