This change introduces a version 3 of the PSV data that includes support
for the name of the entry function as an offset into StringTable data to
a null-terminated utf-8 string.
Additional tests were added to ensure that the new value was properly
serialized/deserialized from object data.

Add DXIL module flag bit offset for SHADER_FEATURE_FLAG.
Added DXIL_MODULE_FLAG for DXIL module flag which does not have feature flag.
Use DXILModuleFlags for ComputedShaderFlags instead of
ShaderFeatureFlags.
ComputedShaderFlags::getFeatureFlags() was added to get FeatureFlags.
Rename DXContainerGlobals::getShaderFlags to DXContainerGlobals::getFeatureFlags.
Fixes#57925
For DirectX, program signatures are encoded into three different binary
sections depending on if the signature is for inputs, outputs, or
patches. All three signature types use the same data structure encoding
so they can share a lot of logic.
This patch adds support for reading and writing program signature data
as both yaml and binary data.
Fixes#57743 and #57744
The DXContainer pipeline state information encodes a bunch of mask
vectors that are used to track things about the inputs and outputs from
each shader.
This adds support for reading and writing them throught he YAML test
interfaces. The writing logic in MC is extremely primitive and we'll
want to revisit the API for that, but since I'm not sure how we'll want
to generate the mask bits from DXIL during code generation I didn't want
to spend too much time on the API.
Fixes#59479
The pipeline state data captured in the PSV0 section of the DXContainer
file encodes signature elements which are read by the runtime to map
inputs and outputs from the GPU program.
This change adds support for generating and parsing signature elements
with testing driven through the ObjectYAML tooling.

When writing this initially I missed including the resource stride.
This change adds the resources stride to the serialized value.
I've also extended the testing and error reporting around parsing PSV
information. This adds tests to verify that the reader produces
meaningful error messages for malformed DXContainer files, and a test
that verifies the resource stride is respected in the reader even if
the stride isn't an expected or known value (as would happen if the
format changes in the future).
This is part of #59479.

DirectX shader pipeline state validation information is a fairly
complicated to serialize data structure. This patch adds the first bit
of support for reading and writing the runtime info structure which
comes first in the encoded data.
Subsequent patches will flesh out the remaining fields of the data
structure.
There is no official documentation for the format, but the format is
roughly documented in the code comment here:

DXContainer files contain a part that has an MD5 of the generated

part data and hash iteself in preparation for adding hashing support to
DirectX code generation.

DXContainers contain a feature flag part, which stores a bitfield used
to denote what underlying hardware features the shader requires. This
change adds feature flags to the DXContainer YAML tooling to enable
testing generating feature flags during HLSL code generation.

This patch adds a the first bits of support for a yaml representation
of dxcontainer files.
Since the YAML representation's primary purpose is testing
infrastructure, the yaml representation supports both verbose and a
more friendly format by making computable sizes and offsets optional.
If provided they are validated to be correct, otherwise they are
computed on the fly during emission.
As I expand the format I'll be able to make more size fields optional,
and I will continue to make the format easier to work with.
