Kristiyan Kostadinov 981c28c15f refactor(compiler-cli): do not emit signal unwrap calls in versions older than 17.2 (#54423) ...

In order to allow both signals and non-signals in two-way bindings, we have to pass the expression through `ɵunwrapWritableSignal`. The problem is that the language service uses a bundled compiler that is fairly new, but it may be compiling an older version of Angular that doesn't expose `ɵunwrapWritableSignal` (see https://github.com/angular/vscode-ng-language-service/issues/2001).

These changes add a `_angularCoreVersion` flag to the compiler which the language service can use to pass the parsed Angular version to the compiler which can then decide whether to emit the function.
