In ESM5 decorated classes can be indicated by calls to `__decorate()`. Previously the `ReflectionHost.findDecoratedClasses()` call would identify helper calls of the form: ``` SomeClass = tslib_1.__decorate(...); ``` But it was missing calls of the form: ``` SomeClass = SomeClass_1 = tslib_1.__decorate(...); ``` This form is common in `@NgModule()` decorations, where the class being decorated is referenced inside the decorator or another member. This commit now ensures that a chain of assignments, of any length, is now identified as a class decoration if it results in a call to `__decorate()`. Fixes #27841 PR Close #27848
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.
