Add support to inject a library-related service mocker

[satanTime]

The idea is to provide support ts-mockery as peerDependency and to allow user to mock everything ng-mocks mock with a specified library.

For example adding in a setup script of karma or testing framework

import 'ng-mocks/mockery/jasmine';

or

import 'ng-mocks/mockery/jest';

and in that case we use specified library to mock methods instead of setting () => {} everywhere.
