Philip Rebohle 7549d70fbf vkd3d: Fix compiler errors when using vkd3d_atomic_ptr_store_explicit. 
Atomic stores do not return anything, so we cannot cast to void* here.

Philip Rebohle 1563b80852 include: Fix various issues with atomic CAS. 
- fail/success memory orders exist for a reason, we can't
  e.g. do release on fail since it's a read-only operation
- silence some warnings about pointer->integer casts
- fix linker errors on mingw by marking functions as static

Joshua Ashton 033f76e3ae vkd3d: Define our own memory orders 
We shouldn't potentially override stuff in the std library and this allows us to map directly to __ATOMIC_* memory orders which is more correct.

Joshua Ashton cd5d01d25c vkd3d: Refactor atomics 
There is no stdatomic available on MSVC so let's clean things up.

This moves all the atomic helpers to vkd3d_atomic.h and implements all platform's spinlocks in entirely the same way.
