This change replaces kernel AST declarations of fields and functions with bytecode declarations. Size of dilp files is reduced by 11-12%. Startup latency: Time to the first full frame: 1.945s -> 1.687s FinalizeClass: 554ms -> 277ms FinishClassLoading: 296ms -> 156ms There are following regressions in bytecode mode, which will be fixed in future: * dart:mirrors are not supported yet (implementation of mirrors relies on reading kernel AST in certain cases). As the result, lib_2/mirrors/* tests fail. * native extensions are not supported yet (annotations on libraries and classes in AST are cleaned up as they could reference members which are now removed from AST). As the result, standalone_2/entrypoints_verification_test test fails. * language_2/spread_collections/const_error_test/* tests fail due to https://github.com/dart-lang/sdk/issues/36286.
