refactor(@angular-devkit/build-angular): deprecate a number of dev-server options

With this change we deprecate a number of dev-server builder options which proxied to the browser builder. This pattern also wrongly assumes that 3rd party browser builders also support all these options.

Configure the below deprecated options directly in the browser builder target options instead.

- aot
- sourceMap
- deployurl
- baseHref
- vendorChunk
- commonChunk
- optimization
- progress
