fs/fs: remove unnecessary FS_REFCOUNT config

Browse Source 
Previously, this config was added to ensure that the size of the struct
file remained unchanged, thereby preventing the Flash memory of
resource-constrained MCUs from being unnecessarily increased.

However, we have now refactored the relationship between struct fd and struct file,
reducing their memory footprint in both Flash and RAM.
Consequently, this config can be removed.

Note that this option will ensure the safety of access to the file
system from multi-tasks (thread A blocking rw(fd), then thread B close(fd)),
the disadvantage is that it will increase the amount of code-size,
there is no need to enable this option if the application could ensure
he file operations are safe.
