Lorenzo Stoakes a9d1f3f2d7 mm/vma: move stack expansion logic to mm/vma.c ...

We build on previous work making expand_downwards() an entirely internal
function.

This logic is subtle and so it is highly useful to get it into vma.c so we
can then userland unit test.

We must additionally move acct_stack_growth() to vma.c as it is a helper
function used by both expand_downwards() and expand_upwards().

We are also then able to mark anon_vma_interval_tree_pre_update_vma() and
anon_vma_interval_tree_post_update_vma() static as these are no longer
used by anything else.
