Lorenzo Stoakes (Oracle) 0c2aa66357 mm: reintroduce vma_desc_test() as a singular flag test
Similar to vma_flags_test(), we have previously renamed vma_desc_test() to
vma_desc_test_any().  Now that is in place, we can reintroduce
vma_desc_test() to explicitly check for a single VMA flag.

As with vma_flags_test(), this is useful as often flag tests are against a
single flag, and vma_desc_test_any(flags, VMA_READ_BIT) reads oddly and
potentially causes confusion.

As with vma_flags_test() a combination of sparse and vma_flags_t being a
struct means that users cannot misuse this function without it getting
flagged.

Also update the VMA tests to reflect this change.
