The packed descriptor index is no longer needed, and causes issues in
case a game sets a root signature, then binds a root descriptor, and
then sets a different root signature which maps the given root parameter
index to a different descriptor since we may now read undefined data
when updating push descriptors.
Fixes#366.

MSDN states that root signatures across multiple stages in a graphics
pipeline must be identical, but the D3D12 runtime does not validate
this and mixing different root signatures results in undefined
behaviour, so just taking this from the VS should be safe.

We only need to know the pipeline layout for pipeline variant
creation. We are not holding a strong reference to the root
signature anyway, which may be problematic, but this should
not introduce a regression.

Offset buffer state might be the only relevant difference between two
descriptors. We won't need to copy descriptors, but the offsets must be.

Otherwise, we may run into issues with an app accessing stale resource
or pointers. NULL descriptors are handled in OMSetRenderTargets.

The struct definitions were identical anyway, and unifying
these will prevent unnecessary code duplication.

The only currently known use case for this requires us to actually
perform the dispatch operation. Executing more than one indirect
dispatch command is not meaningful, however there might be
differences in behaviour in case the indirect count is zero.

This logic has to be the same as in d3d12_command_list_update_descriptor_table_offsets,
since not all active descriptor tables are necessarily used by the root signature.
Fixes an assert in the StarsX IrradianceMap demo (Github issue #347).

This makes headers a dependency rather than a generator target.
This also means we get proper dependency tracking of them between projects.

Rename so objects we build so we don't conflict with vkd3d and don't
accidentially attempt to be built against Wine natively (it won't work).
Not quite ready for a 2.0 release yet, but bump the version to reflect
the intent. This creates a new timeline, completely separate from vkd3d.

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.

We will not have offset information for root descriptors, so
we can still only use them with four-byte aligned SSBOs.

Introduces 'extra' bindings to bindless sets which can be used to
bind additional storage buffers to the pipeline, which will occur
before the bindless descriptor array in the descriptor set.

We cannot rely on alignment analysis since games are buggy and screw up
RAW vs structured on occasion.
