devtool: add build-sdk subcommand
Add a build-sdk command which is only available within the extensible SDK that builds a derivative extensible SDK. The idea is recipes in the workspace become a part of the new SDK - for example, this allows taking a vendor provided SDK, adding a few libs and then producing a new SDK with those included. When normally building the extensible SDK, the workspace is excluded; here we need to copy into the new SDK (renaming it in the process); the recipes' task signatures become locked and thus the sources are no longer needed, so they are removed along with the workspace bbappends which would interfere with the locked signatures. Additionally we need to just copy the configuration files (i.e. local.conf and auto.conf) rather than filtering and appending to them since that work has already been done when constructing the original SDK. The extra sstate artifacts from workspace recipes are also determined and copied into the new SDK in minimal mode (on the assumption that you won't set up a new sstate mirror). This reuses some code from build-image, so that needed to be generalised to allow that. Implements [YOCTO #8892].
