[stable][cfe] Issue 60121: Fix bug with isWildcard flag for formals.

Issue description: Users are finding that their debug variables are
evaluated to the wrong values and it's due to wildcard variables being
included, but being unable to be evaluated. Wildcard variables shouldn't
be able to be evaluated in the first place.

What is the fix: Correctly propagate the `isWildcard` flag in the CFE to
formal parameters. The VM uses this flag to determine if the variable
can be excluded from debugging evaluation. The flag is now set correctly
with the fix and won't appear in VM debug.

Why cherry-pick: This is causing debug variables to be evaluated
incorrectly because wildcard variables are appearing in the debug panel
of variables and shouldn't be.

Risk: Low, fixes wildcard variables that are formal parameters and touches no other code. This is code that should've been in the feature from the start.

Dart

An approachable, portable, and productive language for high-quality apps on any platform

Dart is:

  • Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.

  • Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
