ShellPkg: Expand special output file to include "NULL" and case insensitive
As per ECR 1349 change in UEFI Shell Specification 2.2, expanding
a special output file name to include "NULL". Previously it only
supported "NUL" as a special output file and it was case sensitive.
With this change both "NUL" and "NULL" are special output file and
checked as case insensitive.
