EDK II Specifications for edk2-stable201903 tag

["Kinney, Michael D" <michael.d.kinney@intel.com>]

Hi Liming and Bob,

I see several EDK II specification updates.

I do not see consistent updates to the Revision History
In the README.md with link to the BZ for the document
change.  Please make sure all revision histories are
up to date with BZ links, and as each BZ is closed put
the links to commits made in the BZ.  This allows anyone
reading the documents to follow the link to the BZ from
the Revision History, review the change request and follow
the links to the commits in GitHub and the easily view the
document changes.

Do you want released versions of these documents to 
align with the edk2-stable201903 tag?  The document
release process is documented here:

https://github.com/tianocore-docs/edk2-TemplateSpecification/wiki/TianoCore-Documents-Releasing

If so, please enter BZ for each document with the
requested release version number along with the 
SHA hash of on master the release branch is being
requested.

Thanks,

Mike
