Delegates the SDK's TaskEnvironmentDefaults and TaskEnvironmentHelper shims to MSBuild's public TaskEnvironment.Fallback / CreateWithProjectDirectoryAndEnvironment APIs (dotnet/msbuild#13462), and drops the now-unused ProcessTaskEnvironmentDriver polyfill. Pipelines are expected to fail until the consumed MSBuild API target version is bumped to a build that exposes these APIs. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
