Pawel Kozlowski 99886bd159 fix(ivy): unify checkNoChanges logic with the view engine (#28366)
This commit unifies handling of the "check no changes" mode between
ngIvy and the view engine. More specifically:
- check no changes can be invoked before change detection in ivy;
- `undefined` values are considered equal `NO_CHANGES` for the "check no changes"
mode purposes.

Chanes in this commit enables several tests that were previously running only in ivy
or only in the view engine.
