These were broken by command re-ordering. The first problem was that
the Framebuffer RenderNode was not correctly being flagged as dirty.
This is fixed by keeping a serial instead of a bool to track the
RenderNode's cleanliness. The second issue was that an image layout
transition was being set with incorrect bits. Fix this by using the
correct access mask.

This fixes angle_perftests's Vulkan render test.

The default heap ordering is to return the greatest element in the
heap. Since the handle allocator expects a minimal return value on
a new allocation, this caused a bug. The bug is triggered by reserving
handles, allocating new handles, then freeing the handles and
allocating again with the same allocator. Fix the bug by using
std::greater instead of std::less, which will make the heap
return the smallest value instead of largest.

Also adds some logging debugging code for the handle allocators.

Recent NVIDIA drivers have a bug where a specific optimized path
inside the driver doesn't handle constant register 0 correctly. Work
around this by starting constant register allocations from 1. This
should make sure that the bug doesn't trigger if the ordering of
uniforms is changed on the D3D backend.

The repro case seems to require some specific driver state to be set
that's used inside Chromium. Because of this we have not been able to
develop a standalone test case so far.

The maximum number of available uniform slots is reduced accordingly.
This should not take them below required minimums in the spec.

This simplifies the pipeline state object caching. We will not need
to use any extra bits to cache based on program properties - instead
all programs will be compatible. The pipeline layout strucutre is
described in the design docs. It currently only has two bind groups:
the first for default uniforms, and the second for Textures. In the
future we might re-organize this to handle driver uniforms, dynamic
push constants, and/or program uniform buffers with ES 3.0.

Instead of storing only the Textures that are required by a Program,
we reserve space for the maximum possible Texture units. We might have
to revisit this very simple design in the future to support texture
arrays, which are handled specially in Vulkan.

This introduces a new CommandBufferNode class. Nodes are linked
together to form a graph based on their dependencies. When the app
triggers a readback or swap, the graph is flushed entirely. This
sends the queued ANGLE Vulkan work to the Vulkan queue which is
then processed on the GPU with the right dependencies.

This design allows us to save on some unnecessary RenderPass creation
and also allows us to know what load/store ops to use. It also allows
us to take advantage of the Vulkan automatic RenderPass transitions
for performance. Load/Store ops and automatic transitions will be
implemented in later patches.
