James HilliardandTom Rini 5e41a5deb4 env: migrate static flags list to Kconfig
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.
