buildhistory: improve support for extensible SDK

* Ensure extensible SDK and standard SDK go into their own directories
* Record extra extensible SDK variables
* Write sstate-package-sizes.txt and sstate-task-sizes.txt files so you
  can analyse the size of the contents
* Add BUILDHISTORY_SDK_FILES (similar to BUILDHISTORY_IMAGE_FILES) and
  default it to pick up config files installed in the extensible SDK
