fix(ddc): router, compiler, web worker fixes for DDC

Also enable DDC checks across all non-web worker playground apps. We are
now down to 2 DDC errors across all of them. The remaining two need to be
fixed in package:analyzer, not in angular.

BREAKING CHANGE:

- there's a chance of breakage as router's Instruction constructor
  signature changed.

Closes #6693
