MdePkg/Test: Add SafeIntLib and BaseLib Base64 unit tests
https://bugzilla.tianocore.org/show_bug.cgi?id=2505
* Add unit tests for SafeIntLib class
* Add unit tests for BaseLib Base64 conversion APIs.
* Add Test/MdePkgHostTest.dsc -to build host based unit
tests
* Update MdePkg.dsc to build target based tests for
SafeIntLib and BaseLib
* Update MdePkg.ci.yaml to build and run host based
tests for SafeIntLib and BaseLib
