Environment callbacks can already be configured from Kconfig with CONFIG_ENV_CALLBACK_LIST_STATIC, but static environment flags still require board headers to define CFG_ENV_FLAGS_LIST_STATIC. Add CONFIG_ENV_FLAGS_LIST_STATIC and use it as the only board-provided static environment flags list. Convert the remaining default-config users from CFG_ENV_FLAGS_LIST_STATIC to defconfig settings and drop the legacy header macro from ENV_FLAGS_LIST_STATIC. Move the environment flags format documentation out of README and into the developer environment documentation. Include the format in the Kconfig help as well. This lets boards configure writeable-list policy and type validation from defconfig without adding a config header solely for env flags. This preserves the behavior of default configs. Header-only cases that were inactive in upstream defconfigs are not converted into defconfig entries: iot2050 can add its list when enabling ENV_WRITEABLE_LIST, and smegw01 can add mmcdev:dw support if the unlocked SYS_BOOT_LOCKED=n configuration is needed.
