Replace the legacy WORKSPACE + p4_infra_deps.bzl dependency system with a MODULE.bazel file. All dependencies now come from the Bazel Central Registry, including grpc 1.80.0-pre1 (no patches needed). Bazel 9 is blocked by grpc 1.80.0-pre1 using native.cc_library (removed in Bazel 9). macOS is blocked by p4c 1.2.5.11 using pipe2() (Linux-only).

Replace the legacy WORKSPACE + pins_infra_deps.bzl dependency system with MODULE.bazel. All deps now come from the Bazel Central Registry where possible; only otg_models and sonic_swss_common remain as non-BCR deps via a module extension. Key changes: - 28 BCR bazel_dep() entries replace ~25 http_archive calls - Delete local gutil/ and p4_infra/ forks; depend on upstream @gutil (BCR 20260309.0) and @p4_infra (pinned to smolkaj/p4-infra bzlmod branch via git_override, pending google/p4-infra#61) - Extract sonic-pins-specific p4_runtime_session / matchers files to new p4rt_test_helpers/ package - C++17 → C++20, Bazel 6.4.0 → 8.2.1 - GMP → boost.multiprecision (single call site in z3_util.cc) - z3 dynamic → z3 static (BCR z3 dynamic has runfiles issues) - Update ~840 #include paths (gutil/gutil/ → gutil/, p4_infra/p4_pdpi/ → p4_pdpi/, gnoi proto → github.com/openconfig/ gnoi/ paths, etc.) - Update golden files for new p4c 1.2.5.11 output - Trim install_dependencies.sh to sonic_swss_common system deps only Not yet working: p4rt_app/ (sonic_swss_common C++20 incompatibility).
