fs: fat: add rename
The implementation roughly follows the POSIX specification for rename() [1]. The ordering of operations attempting to minimize the chance for data loss in unexpected circumstances. The 'mv' command was implemented as a front end for the rename operation as that is what most users are likely familiar with in terms of behavior. The 'FAT_RENAME' Kconfig option was added to prevent code size increase on size-oriented builds like SPL.
