mm/gup: move private gup FOLL_ flags to internal.h
Move the flags that should not/are not used outside gup.c and related into
mm/internal.h to discourage driver abuse.
To make this more maintainable going forward compact the two FOLL ranges
with new bit numbers from 0 to 11 and 16 to 21, using shifts so it is
explicit.
Switch to an enum so the whole thing is easier to read.
