fix(macOS): Hard coding the default frameworks path in order to resolve macOS frameworks

[DennisDyallo]

Description

This pull request updates the Libraries class in Yubico.Core/src/Yubico/PlatformInterop/macOS/Interop.Libraries.cs to use absolute paths for macOS framework references. This change ensures compatibility with the system's directory structure.
This is due to an ongoing issue at MSFT and dotnet, where the .NET runtime is no longer searching the correct framework paths since NET7. This fix works for NET6,7,8,9.

Updates to macOS framework paths:

• Changed the CoreFoundation, IOKitFramework, and WinSCard constants to use absolute paths (/System/Library/Frameworks/...) instead of relative paths (.framework/...) to align with macOS system conventions.

Fixes: #205

• Refactor (non-breaking change which improves code quality or performance)
• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
