Add Windows runner profiles and configuration for Gitea CI

- Introduced Dockerfiles for various Windows runner profiles: C/C++, .NET, Go, and MSYS.
- Added a PowerShell script to start the Gitea runner with appropriate configurations.
- Updated Ansible host variables to include new Windows build root and runner configurations.
- Enhanced the Windows Gitea runner role to support multiple execution modes (linux_podman and windows_mcr).
- Implemented tasks to validate runner execution modes, ensure necessary services are running, and manage Docker containers for Windows runners.
- Created a new task file for managing Windows-specific runner operations.
- Updated the configuration template to dynamically set paths for runner files and cache directories.
