Update for Angular package and sample app to version 14

Description / Motivation

JSS will now use the LTS version of Angular. This comes with some side effects, considering the changes introduced in Angular 13 (https://blog.angular.io/angular-v13-is-now-available-cce66f7bc296)

• sitecore-jss-angular is now built into ESM, no UMD output available.
• sitecore-jss-angular is configured as an angular library. angular.json added, ng test is used to run unit tests.
• karma-typescript no longer used for unit tests in sitecore-jss-angular due to compatibility issues Is karma-typescript compatible with Angular 13+ ? monounity/karma-typescript#589 .
• Test coverage report is no longer written to console, only the html output is generated.
• ComponentFactoryResult interface no longer has componentFactory field as it's no longer needed. The new approach to component creation can be used.
• IE11 no longer supported by JSS angular apps.
• angular sample app uses constants from a dedicated JSON file now, instead of importing them from base package, due to module format conflicts.
• Removed and deprecated imports are removed and the logic corrected to account for the changes.

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)

Great work! See review comments below and some things to mention:

1. Check packages by using npm i, sitecore-jss-angular can't be installed
2. npm run coverage is not working for sitecore-jss-angular
3. Coverage report should be logged to the console as it was before
4. Unit tests coverage is not included in Azure pipelines coverage report, but it should be there as it was before
5. Check package.json files and use latest version everywhere. (^ uses the latest, but anyway it should be explicitly set)
6. There is no way to import something from sitecore-jss-angular if you are using script, it's an issue and we will need to maintain both places (cause you added duplicate)
