CONFIG_NFILE_DESCRIPTORS=0 can no longer be used to disable the file system. NuttX with no file system does not make sense.

Squashed commit of the following:

    configs/:  The few configurations that formerly set CONFIG_NFILE_DESCRIPTORS=0 should not default, rather they should set the number of descriptors to 3.

    tools/:  Tools updates for changes to usage of CONFIG_NFILE_DESCRIPTORS.
    syscall/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    libs/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    include/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    drivers/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    Documentation/:  Remove all references to CONFIG_NFILE_DESCRIPTORS == 0
    binfmt/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    arch/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    net/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    sched/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
