When ngtsc compiles @angular/core, it rewrites core imports to the r3_symbols.ts file that exposes all internal symbols under their external name. When creating the FESM bundle, the r3_symbols.ts file causes the external symbol names to be rewritten to their internal name. Under ngcc compilations of FESM bundles, the indirection of r3_symbols.ts is no longer in place such that the external names are retained in the bundle. Previously, the external name `ɵdefineNgModule` was explicitly declared internally to resolve this issue, but the recently added `setClassMetadata` was not declared as such, causing runtime errors. Instead of relying on the r3_symbols.ts file to perform the rewrite of the external modules to their internal variants, the translation is moved into the `ImportManager` during the compilation itself. This avoids the need for providing the external name manually. PR Close #27055

* This file exists to support compilation of @angular/core in Ivy mode.

|
|
* When the Angular compiler processes a compilation unit, it normally writes imports to
|

* @angular/core. When compiling the core package itself this strategy isn't usable. Instead, the
|
|
* compiler writes imports to this file.
|
|
*
|
|
* Only a subset of such imports are supported - core is not allowed to declare components or pipes.
|
|
* A check in ngtsc's translator.ts validates this condition. The translator is responsible for
|
|
* translating an external name (prefixed with ɵ) to the internal symbol name as exported below.
