This adds 60 bytes to both structures. It eliminates "False Sharing"
for atomic operations (see wikipedia).

Some GL applications, including Blender, are producing rendering
artifacts due to missing resource state barriers.
The d3d12_context keeps track of all resources bound as shader resource
or constant buffers. If any of these resources are used for Copy,
Resolve, or Clear source/target, the context tracking must be updated
so the correct state can be restored before the next draw call.
This change is something of a big hammer. Essentially, if a resource
currently bound as an SRV or CBV gets used for a non-shader access, a
flag is set in the context that invalidates all bindings of the same
type on the same shader stage. Thus the next Draw execution refreshes
the shader views and state transitions state before invoking Draw on the
command list.
A more elegant (and complex) fix would limit the invalidation to
resource state only, rather than also forcing a recreation of resource
views. It is unclear right now whether it is worth the time to
implement a more elegant fix.

Instead of calling this functions again to unbind trailing slots,
extend it to do it when binding. This reduces CPU overhead.
A lot of drivers ignore "start" and always unbind all slots after "count".
Such drivers don't need any changes here.

For C++ code, we shouldn't use {0}, instead use {} to default-
initialize everything. For code with nested structs/unions, make
sure there's enough braces to appropriately scope initialization.

This driver will allow running OpenGL and OpenCL on top of Gallium
for any hardware supporting Microsoft's Direct3D 12 on Windows 10.
This is the combination of a lot of commits from our development branch,
containing code from several authors.
