Add OneLake workspace client factory

[Akın Soysal (akeensoysal)]

Summary

Add DataLakeFileSystemClient::CreateForOneLakeWorkspace so OneLake consumers can construct a validated workspace-scoped DFS/Blob client pair without duplicating Fabric cloud, ring, regional, and workspace-host resolution.

• validate compact and hyphenated workspace GUIDs plus supported OneLake endpoint grammar
• construct explicit ring-aware workspace DFS and Blob endpoints
• reject unsafe retry, customer-key, audience, credential, and URL configurations before token or transport activity
• preserve workspace Blob hosts and pipelines on rename-returned clients
• add offline endpoint, auth, routing, rename, and DNS-boundary tests
• add a strict redacted live-contract harness for the 4-cloud x 4-ring x DFS/Blob matrix
• add changelog and DefaultAzureCredential sample coverage

Related to #7274.

Tracking

• Private Link implementation: ADO 5112511

Verification

• clean WARNINGS_AS_ERRORS=ON build of Data Lake unit tests, live harness, and sample
• OneLakeWorkspaceClientTest.*: 22/22 passed
• registered OneLakeWorkspaceEndpointHarness: passed
• offline 32-case validate matrix: 32/32 passed, 0 probes
• offline 32-case mock matrix: 32/32 passed, exact DFS/Blob hosts
• existing Data Lake rename playback tests: 4/4 passed
• LLVM 11 formatting and git diff --check: passed
• pinned AMQP test broker (d82a8645) restores from an empty cache through public Azure mirrors, builds for net8.0, starts, listens on port 25672, and accepts a connection
• fork Core CI skips credentialed Cargo feed setup and uses vendored uAMQP (199/199 tests passed); trusted builds retain Rust AMQP with CFS routing

Pending validation and release conditions

• Azure Storage maintainers and OneLake service owners confirm the API placement and supported cloud/ring matrix.
• The generated Data Lake APIView completes the required Azure SDK API review. For this targeted additive change, C++ language-architect approval is sufficient unless the change is escalated to the Architecture Board.
• Before release, OneLake service-owned live validation passes every owner-approved cloud/ring/API-family combination with no failures or skips. If the proposed 4 x 4 x 2 matrix is confirmed, the required result is 32 passed, 0 failed, 0 skipped.

CDC will update its Azure SDK submodule to the first upstream Azure SDK for C++ release tag containing this API; it will not pin a commit from this fork.

Pull request overview

This PR adds first-class Microsoft Fabric OneLake workspace support to azure-storage-files-datalake by introducing a validated factory (DataLakeFileSystemClient::CreateForOneLakeWorkspace) that resolves ring/cloud/workspace-scoped DFS+Blob endpoints and returns a correctly paired client configuration. It also expands test coverage (unit + offline harness) and includes a small set of ancillary changes to AMQP tests and CI to support fork scenarios.

Changes:

• Added DataLakeFileSystemClient::CreateForOneLakeWorkspace with strict URL/workspace validation and explicit construction of workspace DFS/Blob endpoints.
• Updated rename-result client construction to preserve the workspace blob host/pipeline behavior.
• Added extensive unit tests plus a CTest + Python harness for validating/mock-probing the cloud/ring/API-family endpoint matrix; updated sample and build/pipeline wiring.
