test(forms): split Forms example app into Reactive and Template-driven ones (#41108)
One of the main goals of the bundling tests is to verify that unused symbols are tree-shaken away in prod bundles. Currently both Reactive and Template-driven test apps are merged into one. In order to make these tree-shaking tests even more useful, this commit splits exiting test app into two, so that we can further optimize sets of symbols that should be retained in both scenarios. PR Close #41108
