Load the list of C preprocessor macros that are options in the configuration file (`mbedtls/mbedtls_config.h` or `psa/crypto_config.h`), and the list of C preprocessor macros that are defined in `*adjust*.h` but are not public options (derived internal macros). The new module `config_macros` supports both querying the current tree and querying historical data saved by `save_config_macros.sh`, with the same query interface. The part that queries historical data subsumes the `config_history` module. Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com>
