This change removes the internally provided ZoneJS-based change detection scheduler. This makes Angular Zoneless by default and allows tree-shaking of the Zone change detection providers.

BREAKING CHANGE: Angular no longer provides a change detection scheduler for ZoneJS-based change detection by default. Add
provideZoneChangeDetection to the providers of your bootstrapApplication function or your AppModule (if using bootstrapModule). This provider addition will be covered by an automated migration.

refactor(core): Update tests for zoneless by default

This updates tests and examples only to prepare for zoneless by default.

These changes were identified and made as part of angular#63382. Anything that
failed gets `provideZoneChangeDetection` unless the fixes were easily
and quickly determined.

refactor(core): Make the zoneless-by-default change a flag flip

This makes the zoneless-by-default change a flag flip that can be
individually enabled in tests, createApplication, and bootstrapModule
for gradual rollout. In addition, the "require on CD provider" check is
also made individually flippable for gradual rollout.

feat(@schematics/angular): Applications are zoneless by default
7d219e3 
This change updates applications to omit the ZoneJS dependency by
default. It depends on angular/angular#63382,
which allows us to also exclude the `provideZonelessChangeDetection`
provider.

This change also includes the addition of `provideZoneChangeDetection`
in the `initTestEnvironment` when ZoneJS is detected in the
configuration (either on window or in the polyfills).
