This allows `dart compile` to be used from the build root without a
fully built SDK.
Abstract out executable and dill retrieval in Sdk getters similar to how
snapshot retrieval was abstracted out.
Remove the hostDartAotRuntime parameter to generateKernelHelper, since
all callers always passed the same variable from generate.dart, and
instead retrieve it using Sdk.dartAotRuntime.
Remove all the top-level variables that contained paths in
dart2native.dart and generate.dart and replace their uses with
the appropriate Sdk getter.
