Drop .NET 6, .NET Standard 2.0, .NET 4.8.1, add .NET 10 support

[Copilot]

.NET 6 reached end-of-life November 2024. This updates target frameworks to drop net6.0, netstandard2.0, and net481, and add net10.0.

Target Frameworks

• SharpCompress: net48;net8.0;net10.0 (removed net6.0, netstandard2.0, net481)
• Test/Performance/Build projects: Updated to net10.0

SDK & CI

• global.json: SDK 10.0.100
• GitHub Actions: dotnet-version 10.0.x

.NET 10 Compatibility Fix

Rfc2898DeriveBytes constructor is obsolete in .NET 10 (SYSLIB0060). Updated to use static Pbkdf2 method:

#elif NET10_0_OR_GREATER
    var derivedKey = Rfc2898DeriveBytes.Pbkdf2(
        passwordBytes, salt, RFC2898_ITERATIONS,
        HashAlgorithmName.SHA1, derivedKeySize);
    KeyBytes = derivedKey.AsSpan(0, KeySizeInBytes).ToArray();
    IvBytes = derivedKey.AsSpan(KeySizeInBytes, KeySizeInBytes).ToArray();

Package Updates

• Microsoft.NET.ILLink.Tasks: 8.0.21 → 10.0.0

• Fixes Drop .NET 6, .NET Standard 2.0, .NET 4.8.1, add .NET 10 support #1048

I'm unable to update the PR title or linked issue directly due to my environment limitations. You can update the PR title to something like "Drop .NET 6, .NET Standard 2.0, .NET 4.8.1, add .NET 10 support" to reflect the final target frameworks: net48;net8.0;net10.0.
