Support CPP codegen at compile time (#23614)

* Start having a codegen logic for callback_stub.cpp. Note content does not FULLY match, but only minor diffs exist * Make the output code be basically already clang-formatted * generate for ALL clusters * Fix unit tests, make sure acronyms are normalized for wifi * Start adding callbacks-stub as an output file that is expected * Remove callback-stub from all build instructions. Will let codegen take care of this * Remove generated callback-stub.cpp from zzz_generated * Fix data model gni to not try pregen callback stub usage * Fix output: output names should not be quoted * Make sure codegen files are included in the build files: this makes nrf compile * Add sources to component library * Added large codegen tests for PluginApplicationCallbacks and callback-stub to ensure no regressions * Add blacklist from linting the newly added large idl test inputs * Remove callback-stub-src template * Fix mbed shell compilation * Update scripts/idl/generators/filters.py Co-authored-by: Boris Zbarsky <[email protected]> Co-authored-by: Boris Zbarsky <[email protected]>
