This uses optional new/const and `=` in named argument defaults.
All changes are automated, except for:
- utils/dartdevc/BUILD.gn: run DDC build scripts with --preview-dart-2
- pkg/dev_compiler/tool/patch_sdk.dart: add a TODO that Analyzer doesn't
supporting implicit const in libraries.dart
- pkg/dev_compiler/tool/input_sdk/libraries.dart: was not formatted due
to the aforementioned Analyzer bug
- tools/bots/test_matrix.json: run DDC sourcemap suite in Dart 2 mode
- pkg/pkg.status: skip pkg/dev_compiler if running in Dart 1 mode

Highlights
* compile one module at a time
* use summaries to speed up compiles
* use command runner so we can add more commands later
* some long needed renames and file organization
* various other technical debt has been addressed
Lowlights
* lost node.js runner/tests (node output format still supported)
* possibly lost some closure support/workarounds (format still supported)
* needs more end-to-end tests of the new system

this also starts using compiled code in dart_core.js (just copy+paste for Object)
visitClassDeclaration was getting rather long, so it's now refactored to make the flow more clear.
