Alexander Markov 61f0f5bc43 [vm/bytecode] Declare members in bytecode 
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.
