     Allow Starlark rules to be able to use the `exec_compatible_with`

Incompatible changes:

  - Flip --incompatible_windows_escape_jvm_flags to true. See
    https://github.com/bazelbuild/bazel/issues/7486
  - Flip --incompatible_windows_style_arg_escaping to true.  See
    https://github.com/bazelbuild/bazel/issues/7454
  - --incompatible_windows_escape_jvm_flags is enabled by default,
    and the flag no longer exists
  - `--incompatible_no_output_attr_default` is enabled by default.
  - --incompatible_depset_union is enabled by default.
  - Python rules now determine the Python runtime using toolchains
    rather than `--python_top` and `--python_path`, which are
    deprecated. See
    [#7899](https://github.com/bazelbuild/bazel/issues/7899) for
    information on declaring Python toolchains and migrating your
    code. As a side-benefit, this addresses #4815 (incorrect
    interpreter version used) on non-Windows platforms. You can
    temporarily opt out of this change with
    `--incompatible_use_python_toolchains=false`.

    addresses #4815 (incorrect interpreter version used) on
    non-Windows platforms. You can temporarily opt out of this change
    with `--incompatible_use_python_toolchains=false`.

New features:

  - Windows, Python: the --incompatible_windows_escape_python_args
    flag (false by default) builds py_binary and py_test targets with
    correct command line argument escaping.
  - cquery supports --output=build

Important changes:

  - Allow debugging C++ features logic.
  - The --ios_multi_cpus, --watchos_cpus, --macos_cpus and tvos_cpus
    are now additive. This means that you can now split the
    --ios_multi_cpus=arm64,armv7 into --ios_multi_cpus=arm64 and
    --ios_multi_cpus=armv7.
  - Generated Go protobufs now depend on
    //net/proto2/go:proto_gendeps instead of //net/proto2/go:proto
  - Add new options --cs_fdo_instrument and --cs_profile to support
    LLVM's context-sensitive FDO (CSFDO).
  - Bazel C++ compile/link Starlark API. Can be used with
    experimental flag
    --experimental_cc_skylark_api_enabled_packages=<package_path>,<pac
    kage_path2>.
  - `cc_toolchain.static_runtime_lib` and
    `cc_toolchain.dynamic_runtime_lib` are now exposed to Starlark.
  - New flag `--incompatible_no_kwargs_in_build_files`. See
    https://github.com/bazelbuild/bazel/issues/8021
  - struct.to_proto() converts dict into proto3 text message (map<,>).
  - Android resource conflicts will no longer be reported between a
    strong attr resource and a weak attr resource, if the weak attr
    does not have format specified.
  - Flag `--incompatible_static_name_resolution_in_build_files` is
    added. See https://github.com/bazelbuild/bazel/issues/8022
  - Add --incompatible_objc_framework_cleanup to control whether to
    enable some objc framework cleanup that changes the API.
    Specifically, the cleanup changes the objc provider API
    pertaining to frameworks.  This change is expected to be
    transparent to most users unless they write their own Starlark
    rules to handle frameworks.  See
    https://github.com/bazelbuild/bazel/issues/7594 for details.
  - Added --incompatible_remove_binary_profile to disable the old
    binary
    profiles. Instead use the JSON profile format:
    https://docs.bazel.build/versions/master/skylark/performance.html#
    json-profile
  - Introducing --execution_log_binary_file and
    --execution_log_json_file that output a stable sorted execution
    log. They will offer a stable replacement to
    --experimental_execution_log_file.
  - Flag `--incompatible_disallow_old_octal_notation` is added. See
    //github.com/bazelbuild/bazel/issues/8059
  - Removes the
    --incompatible_disable_genrule_cc_toolchain_dependency flag.
  - Android resource conflicts will no longer be reported between a
    strong attr resource and a weak attr resource, if the weak attr
    does not have format specified.
  - Incompatible flag
    `--incompatible_make_thinlto_command_lines_standalone` has been
    added. See https://github.com/bazelbuild/bazel/issues/6791 for
    details.
  - objc_library does not support resource attributes any more.
    Please read #7594 for more info.
  - The `outputs` parameter of the `rule()` function is deprecated
    and attached to flag `--incompatible_no_rule_outputs_param`.
    Migrate rules to use `OutputGroupInfo` or `attr.output` instead.
    See https://github.com/bazelbuild/bazel/issues/7977 for more info.
  - New platform_mappings ability to allow gradual flag to
    platforms/toolchains migration. See also
    https://github.com/bazelbuild/bazel/issues/6426
  - Added support for compiling against fully qualified R classes
    from aar_import dependencies.
  - --tls_enabled flag is deprecated. Please provide 'grpcs' as a
    scheme in the URLs if TLS should be used for a remote connection.
  - Adds
    incompatible_disallow_rule_execution_platform_constraints_allowed,
     which
    disallows the use of the "execution_platform_constraints_allowed"
    attribute when defining new rules.
  - Flag `--incompatible_restrict_named_params` is added. See
    https://github.com/bazelbuild/bazel/issues/8147 for details.
  - The glob function has a new argument `allow_empty`. When set to
    False, the glob fails when it doesn't match anything.
  - Adds the "disable_whole_archive_for_static_lib" feature to allow
    turning off legacy_whole_archive for individual targets.
  - C++ Starlark API for compilation and linking is no longer
    whitelisted
  - Update visibility advice in build-style
  - --incompatible_disable_objc_provider_resources is now enabled by
    default.
  - Fixed an issue where some `py_runtime`s were incompatible with
    using `--build_python_zip` (#5104).
  - The `outputs` parameter of the `rule()` function is deprecated
    and attached to flag `--incompatible_no_rule_outputs_param`.
    Migrate rules to use `OutputGroupInfo` or `attr.output` instead.
    See https://github.com/bazelbuild/bazel/issues/7977 for more info.
