MdeModulePkg/CapsuleApp: Enhance Capsule-On-Disk related functions.

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1840

1. Add missing '\n' in usage.
2. Fix the dead loop of CapsuleApp -L.
3. Fix the bug that CapsuleApp -OD cannot perform capsules in sub-
folder.
4. Optimize the handling for option -NR and -OD to support both
'CapsuleApp <Capsule> -OD -NR' and 'CapsuleApp <Capsule> -NR -OD'.
5. Check if Capsule-On-Disk is supported by "OsIndicationsSupported"
variable firstly before processing capsules. If not supported, prompt
an error message and quit the process.
