Now the public API does not contain internal types, such as `AbsoluteFsPath` and `EntryPointJsonProperty`. Instead we just accept strings and then guard them in `mainNgcc` as appropriate. A new public API function (`hasBeenProcessed`) has been exported to allow programmatic checking of the build marker when the package.json contents are already known. PR Close #29092
Angular Compatibility Compiler (ngcc)
This compiler will convert node_modules compiled with ngc, into node_modules which
appear to have been compiled with ngtsc.
This conversion will allow such "legacy" packages to be used by the Ivy rendering engine.
