Describe the bug

The source generator project's helper struct EquatableArray will cause a stack overflow if object.Equals() is called.
This is because Equals(this, foo) will call object.Equals(), resulting in an infinite loop.
We need to call the typed version from IEquatable<T> instead.

Regression

Steps to reproduce

Add this test to CommunityToolkit.Mvvm.SourceGenerators Test_SourceGeneratorsCodegen.cs to confirm:

[TestMethod]
public void EquatableArrayTest()
{
    object a = new EquatableArray<string>();
    var b = new EquatableArray<string>();

    Assert.AreEqual(a, b);
}

Before the fix, it will cause a stack overflow.

Expected behavior

You would expect the test to pass without a stack overflow.
