Add scripts for building and managing RustDesk versions

- Implement Build-CustomRustDesk.ps1 to build RustDesk with specified version and configuration.
- Create Get-LastBuiltVersion.ps1 to retrieve the last built version from a state file.
- Add Get-LatestRustDeskVersion.ps1 to fetch the latest version from GitHub releases.
- Develop Invoke-RustDeskPipeline.ps1 to orchestrate the build and deployment process.
- Introduce Publish-Artifacts.ps1 for publishing build artifacts via SMB or SCP.
- Implement Set-LastBuiltVersion.ps1 to update the state file with the last built version.
