[AOT][CmdPal] Enable NativeAOT Compatibility for CmdPal Apps Extension (#39678)

<!-- Enter a brief description/summary of your PR here. What does it
fix/what does it change/how was it tested (even manually, if necessary)?
-->
## Summary of the Pull Request

This PR introduces necessary changes to make the CmdPal.Apps extension
compatible with NativeAOT publishing. The main updates include:

1. Project configuration updates: Added NativeAOT-related properties to
the .csproj.

2. Native interop adjustments:

> - Introduced NativeMethods.json and used
[CsWin32](https://github.com/microsoft/cswin32) to generate P/Invoke
bindings.
> - Replaced some DllImport declarations with source-generated
[LibraryImport] for improved AOT support.
