Fixes dotnet#129961 * Use stack trace data to find the calling assembly. * It is therefore only supportable if stack trace data is available. Block for the same reason under F5 debugging (CoreCLR). This is why it's a breaking change. * Maintain an arbitrary list of methods to skip in stacktraces to make calling this API work in a .cctor. Matches similar arbitrary list in CoreCLR to the extent that is covered by tests. * `canTailCall` is now same between ILC and crossgen2.

Pull request overview
Enables Assembly.GetCallingAssembly() on NativeAOT by deriving the calling assembly from stack-trace metadata, and updates the toolchain/JIT interface to keep tailcall behavior consistent across ILC and crossgen2. The PR also re-enables/extends relevant reflection tests now that NativeAOT support is present.
Changes:
- Implement
Assembly.GetCallingAssembly()for NativeAOT usingStackFrame+DiagnosticMethodInfowhen stack traces are supported. - Gate
GetCallingAssembly()onStackTrace.IsSupported(CoreCLR + NativeAOT) with a new resource string for the error. - Unify
canTailCallhandling by moving logic into the common JIT interface implementation and adjust tests accordingly.
