add_fb_thrift_python_executable (and any add_fb_python_executable call with TYPE dir) produces a directory whose cmake target name is suffixed with .GEN_PY_EXE. Strip that suffix when computing the on-disk output path, and invoke directory outputs via python3 so __main__.py runs. Non-python targets (e.g. fboss-bspmapping-gen) continue to exec directly.
cmake/AsicConfigV2ConfigCli.cmake uses add_fb_thrift_python_executable, which registers the cmake target with a .GEN_PY_EXE suffix. Pass the suffixed name so build can find it; run-helper.py strips the suffix when locating the on-disk output.
Callers can now pass a JSON object of additional cmake defines which is
merged over the hardcoded {CMAKE_BUILD_TYPE, CMAKE_CXX_STANDARD} defaults.
Caller keys win on conflict. Existing callers that do not pass the flag
are unaffected.
range-v3's test suite fails to compile under clang's -Werror,-Wnrvo. Disable it at the cmake level via --extra-cmake-defines.
Implements the design described in "[Data-Driven asic_config_v3 Design](https://docs.google.com/document/d/1yJ1IHX06IOnv5hznau2hdGvtvjvZwPGRsQT2Ft-y3_g/edit?pli=1&tab=t.yk03mogkzncz)" document (approved by Meta for phase 1). Add `fboss/lib/asic_config_v3/` Python package skeleton along with a fully defined CMake build target. This creates the basic infra of the data-driven ASIC config generator (`asic_config_v3`) that will replace the code-driven `asic_config_v2` path. The `gen.py` entry point is included with an empty `_GENERATOR_REGISTRY` so the `fboss-asic-config-v3-gen` target is buildable immediately; registry entries for concrete ASIC families will be added in follow-up commits. Ran `fboss/lib/asic_config_v3/run-helper.sh`.
Add strict JSON schemas for the Broadcom `XGS` ASIC config, the platform config, and the shared vendor common JSONs. Include a validation script that scans the `asic_config_v3` directory tree and validates every matching file against its schema.
