add compiler_input_flags_feature and compiler_output_flags_feature

[PikachuHyA]

This patch adds compiler_input_flags_feature and compiler_output_flags_feature to the features.

follow #22717

By default, the features compiler_input_flags_feature and compiler_output_flags_feature are included through CppActionConfigs.java in the getFeaturesToAppearLastInFeaturesList method.

For reference, see the relevant code here:

Background

I modified tools/cpp/unix_cc_toolchain_config.bzl and found no input and output on macOS when testing #19940 with the new action names c++20-deps-scanning and c++20-module-compile.

As discussed in #22429 (comment), I added these two features to unix_cc_toolchain_config.bzl.

the Windows toolchains already have these features, so no modifications were necessary for windows_cc_toolchain_config.bzl.
