Clean up DEC files:

1) Remove section header comment blocks that do not provide any information
2) Combine PCDs listed in multiple sections into a single section that supports multiple PCD types to reduce maintenance overhead
3) Remove ModuleTypeList comments from [Includes], [Protocols], [Ppis], and [Guids] sections that do not properly describe the module type restrictions.
4) Clean up formatting of GUID structure declarations
5) Remove ".common" from section names if they are not required.
6) Order sections consistently as [Defines], [Includes], [LibraryClasses], [Guid], [Ppis], [Protocols], [PcdsFeatureFlag], [PcdsFixedAtBuild], [PcdsPatchableInModule], [PcdsDynamic], and [PcdsDynamicEx]
