	introduce BootstrapContext for improved server bootstrapping (#63636)

Breaking Changes

core

• The server-side bootstrapping process has been changed to eliminate the reliance on a global platform injector.

  Before:

  const bootstrap = () => bootstrapApplication(AppComponent, config);
  

  After:

  const bootstrap = (context: BootstrapContext) =>
    bootstrapApplication(AppComponent, config, context);
  

  A schematic is provided to automatically update main.server.ts files to pass the BootstrapContext to the bootstrapApplication call.

  In addition, getPlatform() and destroyPlatform() will now return null and be a no-op respectively when running in a server environment.
