These test whether the VMA has stack semantics, i.e. is able to grow
upwards or downwards depending on the architecture.

In order to account for arches which do not support upward-growing stacks,
introduce VMA_GROWSUP whose definition depends on the architecture
supporting it, and use vma_flags_test_single_mask() in vma_flags_can_grow()
to account for this.

No functional change intended.
