mm: remove unused VM_<READfoo> macros and expand other in-place
These VM_<READfoo> macros aren't used very often and three of them aren't used at all. Expand the ones that are used in-place, and remove all the now unused #define VM_<foo> macros. VM_READHINTMASK, VM_NormalReadHint and VM_ClearReadHint were added just before 2.4 and appears have never been used.
