Paul Gschwendtner 4701c7bc54 build: switch to docs-content from examples package (#14612)
With https://github.com/angular/material.angular.io/pull/565 the docs-content will be pulled from the `@angular/material-examples` package. Changes needed on this repository:

* Since we update some styles and logic in favor of simplicity, we need to update the Dgeni templates to conform with these changes.
* Remove the unnecessary `examplesPath` property member because we now compute the `docs-content/` asset paths in a consistent way and don't want to mix up the source locations.
