Add Windows Docker (WSL2) tier-1 integration tests

[roger-zhangg]

Summary

Adds Windows tier-1 integration tests running Docker via WSL2, alongside the existing Linux Finch tier-1 tests.

Changes

New Windows test suites

• tier1-windows-build-1: Python, .NET, Node, main build tests
• tier1-windows-build-2: Java, Rust, Provided, ARM64 build tests
• tier1-windows-build-3: Go, Ruby, Terraform, remaining build tests
• tier1-windows-other: Local invoke, start-api, start-lambda, validate, and other non-build tests

Infrastructure

• WSL2 Docker setup via Vampire/setup-wsl action with Ubuntu 24.04 (installed on D: drive for disk space)
• tests/setup_wsl2_docker.sh: Installs Docker in WSL2 and exposes on TCP
• tests/free_disk_space_windows.sh: Non-blocking cleanup of pre-installed SDKs
• tests/install-maven-gradle.sh, tests/install-terraform.sh: Cross-platform installer scripts
• tests/install-rust.sh: Updated with choco install zig for Windows, --uv flag support
• tests/install-sam-cli-binary.sh: Windows MSI support

• tests/setup-python-uv.sh: Python version management via uv
• tests/setup_testing_resources.py: Consolidated credential setup, ECR login (with retry), and credential clearing into one script

Fixes

• CRLF line ending fix for shell scripts in testdata (Windows checkout adds \r)
• ECR login retry logic for clock skew on Windows
• Terraform provider version updates for test compatibility
• reset_testing_resources.py: Search workspace root for reports, non-fatal account reset errors

Known Issues

Windows durable function tests (test_invoke_durable, test_callback, test_execution) are failing in tier1-windows-other. The durable functions emulator has issues with temp directory handling when Docker runs via WSL2 — a subsequent PR will address this specifically.

Thank you for spliting the setup. Overall, this PR looks good.
I see that there are 3 inline comments about how we slip the build suites but commented but not be sufficient for a future maintainer to notice or understand. We should document the rationale and methodology in one for the README.

still, please ignore the dar test failure in windows tests. Will address that in another PR

Nice work! I'm surprised the windows setup takes only ~90 seconds. Much faster than I thought it would be, must be the caching.
