The AbsoluteModuleStrategy in ngtsc assumed that the source code is formatted as TypeScript with regards to module exports. In ngcc this is not always the case, so this commit changes `AbsoluteModuleStrategy` so that it relies upon a `ReflectionHost` to compute the exports of a module. PR Close #30200
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.
