When sending FIOC_XXXLK to hostfs, hostfs will return -1 by default. For ioctl statements, incompatible instructions should be processed as -ENOTTY by default

When handling errors through ioctl, the error returned by the server is always 0 on the client, because cookie.result is not assigned, the error returned should be in msg->result

This triggers `mm_free_delaylist()` before dumping status in PROTECTED
build, otherwise the `free` command still shows delaylist as `used`.

According to the POSIX standard, `fstat` and `stat` should return 0
(`OK`) on success. This commit changed the underlying `spiffs`
implementation to follow the POSIX standard.
Unbinding `ff_currentcluster` and `f_pos`:
1. Added `ff_pos` in `struct fat_file_s`.
2. Added function `fat_zero_cluster` for doing zeroing for gap
between EOF and new position beyond EOF.
3. Added function `fat_get_sectors` for getting the sector where
`f_pos` is located, allocting new cluster when `f_pos` is beyond
EOF.
4. Modify function `fat_read`, and `fat_write` with above functions.
5. Remove redundant logics in `fat_seek` since now new cluster is
allocated when writing instead of seeking.

pointer comparison is unsigned, when returning -errno will be converted
to a large positive number, can not enter the error handling branch,
therefore, the error code is returned directly and the sem is returned
through the parameters.

Pre-allocated files to avoid allocator access during thread creation
phase, For functional safety requirements, increase
CONFIG_NFILE_DESCRIPTORS_PER_BLOCK could also avoid allocator access
caused by the file descriptor exceeding the limit.
For Task Termination, the time consumption will be reduced ~3us (Tricore TC397 300MHZ):
10.65(us) -> 7.35(us)
NOTE:
This commit will not waste of extra heap, just pre-allocates the list of files for task_group.
