Lorenzo Stoakes (Oracle) bd44d91d0c tools/testing/vma: convert bulk of test code to vma_flags_t 
Convert the test code to utilise vma_flags_t as opposed to the deprecate
vm_flags_t as much as possible.

As part of this change, add VMA_STICKY_FLAGS and VMA_SPECIAL_FLAGS as
early versions of what these defines will look like in the kernel logic
once this logic is implemented.

Lorenzo Stoakes (Oracle) e4fd34b84b tools/testing/vma: add unit tests flag empty, diff_pair, and[_mask] 
Add VMA unit tests to assert that:

* vma_flags_empty()
* vma_flags_diff_pair()
* vma_flags_and_mask()
* vma_flags_and()

All function as expected.

In additional to the added tests, in order to make testing easier, add
vma_flags_same_mask() and vma_flags_same() for testing only.  If/when
these are required in kernel code, they can be moved over.

Also add ASSERT_FLAGS_[NOT_]SAME[_MASK](), ASSERT_FLAGS_[NON]EMPTY() test
helpers to make asserting flag state easier and more convenient.

Lorenzo Stoakes 6aacab308a tools/testing/vma: separate VMA userland tests into separate files 
So far the userland VMA tests have been established as a rough expression
of what's been possible.

Adapt it into a more usable form by separating out tests and shared
helper functions.

Since we test functions that are declared statically in mm/vma.c, we make
use of the trick of #include'ing kernel C files directly.

In order for the tests to continue to function, we must therefore also
this way into the tests/ directory.

We try to keep as much shared logic actually modularised into a separate
compilation unit in shared.c, however the merge_existing() and
attach_vma() helpers rely on statically declared mm/vma.c functions so
these must be declared in main.c.
