improve extension API

- explicitly specified that CDI implementations don't have to accept
  custom implemetations of the `jakarta.enterprise.lang.model` and
  `jakarta.enterprise.inject.build.compatible.spi` interfaces
- moved to Jakarta Annotation 2.1.0-B1, removed `@ExtensionPriority`
  and specified that `@Priority` should be used on extension methods
- specified that `AnnotationBuilder.build` will throw if some members
  of the annotation type were not defined
- adjusted `AnnotationBuilder` so that its methods no longer accept
  varargs; arrays must be passed in explicitly to avoid ambiguity
  in case of single-element arrays
- added `InterceptorInfo` (extending `BeanInfo`) to provide
  information about interceptors, and allowed `@Processing` methods
  to declare parameters of type `InterceptorInfo`
- adjusted `@Enhancement` so that parameters of type  `DeclarationInfo`
  and `DeclarationConfig` can no longer be declared; it is not clear
  what is the full set of matching values
- replaced the use of `Map<String, Object>` in synthetic components
  functions by a dedicated `Parameters` interface
- adjusted synthetic component builders to allow defining a parameter
  of an enum type, as well as using `ClassInfo` for defining a parameter
  of a `Class` type
- improved `ParameterizedType` to provide access to the type (`ClassType`)
  of the generic class, in addition to the declaration (`ClassInfo`)
- replaced abbreviated forms "isn't", "doesn't" and "can't"
  with their longer forms "is not", "does not" and "cannot"
