apollo_deployments: delete base app_configs and the preset-parity test machinery

[nimrod-starkware]

jsonnet build() is the sole source of the node config, so the committed base
app_configs/config.json and the build()-vs-app_configs parity test are dead.
Delete the 21 base *config.json, merged_app_configs/non_default_paths/
test_applicative_matches_app_configs and the applicative_matches_app_configs test,
plus their last-user constants KEYS_TO_BE_REPLACED and BASE_APP_CONFIGS_DIR_PATH
(and the now-dead get_component_config{names,file_paths}), and drop the freed phf
dep. Keep CONFIG_POINTERS/dump()/config_to_preset definitions and the
build_deserializes + *_infra_matches_rust guards (later phases own those).

apollo_deployments 8/8 green; cdk8s synth 31/31 green (build() sole source).
