fs/Kconfig: add CONFIG_FS_PERMISSION option
Add a CONFIG_FS_PERMISSION Kconfig option for future
filesystem permission support infrastructure.
The option depends on CONFIG_SCHED_USER_IDENTITY and
CONFIG_PSEUDOFS_ATTRIBUTES to ensure task credential
tracking and pseudo-filesystem inode ownership/mode
metadata are available before enabling the feature.
The symbol defaults to n to preserve existing behavior
for current configurations.
No runtime permission enforcement is introduced by
this commit.
