This commit removes most tests that were designated as only covering View Engine code. It also removes tag filters from CI and local commands to run tests. In a few cases (such as with the packages/compiler tests), this tag was improperly applied, and certain test cases have been added back running in Ivy mode. This commit also empties `@angular/compiler/testing` as it is no longer necessary (this is safe since compiler packages are not public API). It can be deleted in the future. PR Close #43884
