FS disable FS_LARGEFILE by default

[PetervdPerk-NXP]

Summary

#4193 Introduced LFS support.
However it seems that it's enabled by default as well.
Whereas many applications don't have a need for LFS support i.e. FAT32 is 4GB limited and solutions such as NXFFS, LittleFS and SmartFS run on smaller flash chips.

Therefore I propose to disable this feature by default because it has a big impact on 32bit systems regarding program size and runtime memory size.

If people want to have to large file support on a microcontroller I think it makes sense they have to manually enable this feature.

SMALL is a relative term (and will change over time). So when too many things are roll up into it, it makes for really poor granularity on feature control.

Some defconfig files still should be updated

Seems that SPIFS also need to select an option
