feat: Add Native AOT compilation support for LibreHardwareMonitorLib (#2280)

* feat: Add Native AOT compilation support for LibreHardwareMonitorLib

- Replace non-generic Marshal.GetDelegateForFunctionPointer with generic versions
  (NvApi.cs, NvidiaML.cs, OpCode.cs)
- Replace non-generic Marshal.PtrToStructure/SizeOf with generic versions
  (AtiAdlxx.cs, AmdGpu.cs, Ipmi.cs)
- Replace reflection-based Mono.Posix calls with direct Syscall for non-NETFRAMEWORK
  (OpCode.cs)
- Add DynamicallyAccessedMembers annotations for trim-safe generic marshaling
  (MsiCoreLiquidController.cs, WireViewPro2.cs)
- Add IsAotCompatible, IsTrimmable, and AOT/trim analyzers to csproj for net8.0+
- All changes maintain full backward compatibility with net472/netstandard2.0

Tested: dotnet publish with PublishAot=true on net10.0 win-x64 succeeds.
AOT binary correctly enumerates all hardware and sensors without errors.

* feat: Add conditional compilation for .NET 5.0 or greater in various classes

* feat: Add AOT test project and update workflows for AOT compilation

* Drop test project

* NET5_0_OR_GREATER > NET
