Move static members to another type does not use the correct visibility

Related to https://github.com/dotnet/roslyn/issues/55127

Version Used: Version 17.1.0 Preview 1.1

Steps to Reproduce:

1. Create a new class library, paste the following code in:

class Test
{
    private const string TestConstant = "";

    void M()
    {
        _ = TestConstant;
    }
}

2. Ctrl+. on TestConstant, select "Move static members to another type..."
3. Hit enter to accept the refactoring

Expected Behavior:

Generated code visibility allows for Test to see the constant.

Actual Behavior:

The following code is generated:

internal static class TestHelpers
{
    private const string TestConstant = "";
}

The constant is private, and compilation errors result as the original location cannot see the moved constant.
