MdeModulePkg DxeCore: Handle FFS file with FFS_ATTRIB_CHECKSUM set for not cache memory mapped IO FV.

The code FvCheck() will check FFS file checksum to verify if FFS file is valid when the file is
with FFS_ATTRIB_CHECKSUM set. The whole file will be read through when doing checksum check.
So we can cache FFS file to memory buffer for following checksum calculating first.
And then, the cached file buffer can be also used for FvReadFile.

MdeModulePkg: INF/DEC file updates to EDK II packages

1. Usage information in INF file comment blocks are either incomplete or incorrect.  
This includes usage information for Protocols/PPIs/GUIDs/PCDs/HOBs/Events/BootModes.  
The syntax for usage information in comment blocks is defined in the EDK II Module Information (INF) Specification

MdeModulePkg: INF/DEC file updates to EDK II packages

2. Add MODULE_UNI_FILE file that contains the localized Abstract and Description of a module.
a. Addresses an information gap between INF files and the UEFI Distribution Packaging Specification XML schema
b. There will be an associated update to UPT in BaseTools to consume MODULE_UNI_FILE and associated UNI file during UDP creation that performs the INF -> XML conversion.
c. There will be an associated update to UPT in BaseTools to produce MODULE_UNI_FILE and associated UNI file during UDP installation that performs the XML -> INF conversion.

3. Add Module Extra UNI file that provides the localized Name of a module.
a. [UserExtensions.TianoCore."ExtraFiles"] provides an easy method for a module to specify extra files not listed in [Sources] or [Binaries] sections to be added to a UDP without having to list the files in the UPT package information data file.
b. There will be an associated update to UPT in BaseTools to package up files listed in [UserExtensions.TianoCore."ExtraFiles"] during UDP creation.
c. UNI file contains localized name of a module to go along with the localized Abstract and Description from the MODULE_UNI_FILE.
