fs: separate CONFIG_FS_{FAT, EXT4} from CONFIG_CMD_{FAT, EXT*}
This makes the FAT and ext4 filesystem implementations build if CONFIG_FS_{FAT,EXT4} are defined, rather than basing the build on whether CONFIG_CMD_{FAT,EXT*} are defined. This will allow the filesystems to be built separately from the filesystem-specific commands that use them. This paves the way for the creation of filesystem-generic commands that used the filesystems, without requiring the filesystem- specific commands. Minor documentation changes are made for this change. The new config options are automatically selected by the old config options to retain backwards-compatibility.
