This commit introduces a new API to the ngUpgrade module, which is compatible with AoT compilation. Primarily, it removes the dependency on reflection over the Angular 2 metadata by introducing an API where this information is explicitly defined, in the source code, in a way that is not lost through AoT compilation. This commit is a collaboration between @mhevery (who provided the original design of the API); @gkalpak & @petebacondarwin (who implemented the API and migrated the specs from the original ngUpgrade tests) and @alexeagle (who provided input and review). This commit is an starting point, there is still work to be done: * add more documentation * validate the API via internal projects * align the ngUpgrade compilation of A1 directives closer to the real A1 compiler * add more unit tests * consider support for async `templateUrl` A1 upgraded components Closes #12239
