Ruiyu Ni 0a54cd4431 ShellPkg/help: Fix "-?" may not show manual sometimes ...

Shell core was enhanced to find the manual string in PE resource
section. But the finding algorithm is too strict: If the manual is
written beginning with:
.TH command 0 "descripton of command"

but user types "COMMAND.efi -?". The finding algorithm uses
case-sensitive compare between "command" and "COMMAND" resulting
in the manual cannot be found.

The patch fixes this issue by using existing ManFileFindTitleSection
and ManFileFindSections which compare command case-insensitive.
