refactor(core): expand error logging when the JIT compiler is not available (#42693)
If a decorator or partial declaration has not been AOT compiled, then the compiler is needed at runtime to be able to JIT compile the code. However, it may occur that the compiler is not available, if it has not been loaded into the application. The error that was reported in this case did not provide insight into which class requested compilation, nor did it differentiate between decorators vs. partial declarations. This commit expands the error logging to provide better insight into the class that initiated JIT compilation and offers a specialized error message for partial declarations. This should help a developer better understand why the error occurs and what can be done to resolve it. Closes #40609 PR Close #42693

The directive is part of a library that has been partially compiled.
|

However, the Angular Linker has not processed the library such that JIT compilation is used as fallback.

Ideally, the library is processed using the Angular Linker to become fully AOT compiled.

Alternatively, the JIT compiler should be loaded by bootstrapping using '@angular/platform-browser-dynamic' or '@angular/platform-server',

or manually provide the compiler with 'import "@angular/compiler";' before bootstrapping.`);
