DEVOPSDSC-829 Windows testbenches in container without mounted case folders

[robin-deltares]

This pull request updates the Windows test environment setup for the Delft3D project. The main focus is on improving how the deltares_testbench directory and its dependencies are handled in both Docker and TeamCity build scripts, ensuring a more consistent and maintainable workflow.

The goal is to see if flaky tests become stable when the case directories are inside the container file system instead of mounted through a --bind mount.

Testbench directory and dependency management:

• The entire deltares_testbench directory is now copied into the test environment instead of just the requirements file, ensuring all necessary files are available for testing.
• The Dockerfile now adds the full deltares_testbench directory and installs Python dependencies directly from its pip/win-requirements.txt, simplifying dependency management.

Build and test configuration updates:

• The working directory for running TestBench.py in TeamCity is changed to the root of the testbench (C:\deltares_testbench) for consistency with the new directory structure.
• Docker run parameters now include a volume mount to ensure engine data is available inside the container, improving test reliability.

Pull request overview

This PR modifies the Windows test environment setup to copy the entire deltares_testbench directory into the Docker container rather than mounting it, aiming to improve test stability by avoiding potential issues with bind mounts.

• The entire deltares_testbench directory is now copied into both the TeamCity environment and Docker container instead of just the requirements file
• The working directory for TestBench.py is changed to point to the container's internal path (C:\deltares_testbench)
• A volume mount is added to the Docker run parameters to provide access to engine data
