This commit augments the `FactoryDef` declaration of Angular decorated classes to contain information about the parameter decorators used in the constructor. If no constructor is present, or none of the parameters have any Angular decorators, then this will be represented using the `null` type. Otherwise, a tuple type is used where the entry at index `i` corresponds with parameter `i`. Each tuple entry can be one of two types: 1. If the associated parameter does not have any Angular decorators, the tuple entry will be the `null` type. 2. Otherwise, a type literal is used that may declare at least one of the following properties: - "attribute": if `@Attribute` is present. The injected attribute's name is used as string literal type, or the `unknown` type if the attribute name is not a string literal. - "self": if `@Self` is present, always of type `true`. - "skipSelf": if `@SkipSelf` is present, always of type `true`. - "host": if `@Host` is present, always of type `true`. - "optional": if `@Optional` is present, always of type `true`. A property is only present if the corresponding decorator is used. Note that the `@Inject` decorator is currently not included, as it's non-trivial to properly convert the token's value expression to a type that is valid in a declaration file. Additionally, the `ComponentDefWithMeta` declaration that is created for Angular components has been extended to include all selectors on `ng-content` elements within the component's template. This additional metadata is useful for tooling such as the Angular Language Service, as it provides the ability to offer suggestions for directives/components defined in libraries. At the moment, such tooling extracts the necessary information from the _metadata.json_ manifest file as generated by ngc, however this metadata representation is being replaced by the information emitted into the declaration files.

fake_core is a library designed to expose some of the same symbols as @angular/core, without
requiring compilation of the whole of @angular/core. This enables unit tests for the compiler to
be written without incurring long rebuilds for every change.
@angular/coreis compiled with@angular/compiler-cli, and therefore has an implicit dependency on it. Therefore core must be rebuilt if the compiler changes.- Tests for the compiler which intend to build code that depends on
@angular/coremust have a data dependency on@angular/core. Therefore core must be built to run the compiler tests, and thus rebuilt if the compiler changes.
This rebuild cycle is expensive and slow. fake_core avoids this by exposing a subset of the
@angular/core API, which enables applications to be built by the ngtsc compiler without
needing a full version of core present at compile time.
