There are a number of variables that need to be passed around the program, in particular to the renderers, which benefit from being stored in well defined objects. The new `EntryPointBundle` structure is a specific format of an entry-point and contains the compiled `BundleProgram` objects for the source and typings, if appropriate. This change helps with future refactoring, where we may need to add new properties to this object. It allows us to maintain more stable APIs between the constituent parts of ngcc, rather than passing lots of primitive values around throughout the program. PR Close #26906
