Avoid using bitfield in dxbc::ProgramHeader.
It could potentially be read incorrectly on any host depending on the
compiler.
From [C++17's
[class.bit]](https://timsong-cpp.github.io/cppwp/n4659/class.bit#1)
> Bit-fields are packed into some addressable allocation unit. [ Note:
Bit-fields straddle allocation units on some machines and not on others.
Bit-fields are assigned right-to-left on some machines, left-to-right on
others. — end note ]

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.
Fixes #80175

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.

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:

value() has undesired exception checking semantics and calls
__throw_bad_optional_access in libc++. Moreover, the API is unavailable without
_LIBCPP_NO_EXCEPTIONS on older Mach-O platforms (see
_LIBCPP_AVAILABILITY_BAD_OPTIONAL_ACCESS).
This fixes check-llvm.

DXContainer files contain a part that has an MD5 of the generated
shader. This adds support to the ObjectYAML tooling to expand the hash
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.

Silly mistake, the code here was byteswapping in-place which corrupts
the data structure that is used later to write the correct file.

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.
