This became basically a rewrite in the end, and it got too awkward to
split these commits in any meaningful way.
The goals here were primarily to:
- Support serializing SPIR-V and load SPIR-V.
To do this robustly requires a lot more validation and checks to make
sure end up compiling the same SPIR-V that we load from cache.
This is critical for performance when games have primed their pipeline
libraries and expect that loading a PSO should be fast. Without this,
we will hit vkd3d-shader for every PSO, causing very long load times.
- Implement the required validation for mismatched PSO descriptions.
- Rewrite the binary layout of the pipeline library for flexibility
concerns and performance.
If the pipeline library is mmap-ed from disk - which appears to be
the intended use - we only need to scan through the TOC to fully parse
the library contents.
From a flexibility concern, a blob needs to support inlined data,
but a library can use referential links. We introduce separate
hashmaps which store deduplicated SPIR-V and pipeline cache blobs,
which significantly drop memory and storage requirements.
For future improvements, it should be fairly easy to add information
which lets us avoid SPIR-V or pipeline cache data altogether if
relevant changes to Vulkan/drivers are made.

If we're going to create different SPIR-V files from what the
VkPipelineCache represents, it's meaningless to load it.

Wraps the D3D12 struct with a pipeline library handle.
This is needed if the blob contains references to external data,
which then needs to be resolved.

As per MSDN, SetName is just a wrapper around SetPrivateData and a specific GUID.
Some apps and tools will use this to retrieve their name back.
So instead, just forward the name to Vulkan in the SetPrivateData call.

Version string is used in logging for information purposes, but pipelines blobs and libraries use uint64_t–based commit hash. Using fixed–size integer silences warnings about string length and makes storing build info a little more efficient.
The hash is obtained separately from version string and is shifted to the left by 4 bits if the working tree is dirty.

On systems without extended dynamic state, or for certain pipelines,
it is possible for vk_pso_cache to be VK_NULL_HANDLE, so we need to
check for this during serialization.

This is used extensively by Horizon Zero Dawn, and allows us
to skip the compile screen after the initial first run.
