Import edk2-stable202005vendor/edk2/ca407c7246bf405da6d9b1b9d93e5e7f17b4b1f9vendor/edk2

As with the previous import, only the MdePkg subdirectory has been
brought in. The line-endings were also converted using:

% find . -type f | xargs -n 1 sed -I.BAK -e `printf "s/\r//g"`
% find . -name \*.BAK | xargs rm
