[DirectX] Replace bitfield version in ProgramHeader. (#91797)

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 ]

Additional tests were added to ensure that the new value was properly
serialized/deserialized from object data.

For DirectX, program signatures are encoded into three different binary

so they can share a lot of logic.

[DX] Support pipeline state masks (#66425)

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.

[DX] Fix PSV resource serialization

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

There is no official documentation for the format, but the format is
roughly documented in the code comment here:

DXContainer has a whole bunch of constant values, so I've added a
DXContainerConstants.def file which will grow with constant
definitions, but starts with just part identifiers. I've also added a
utility to parse the part magic string into an enum, and converted the
code to use that utility and the enum instead of the part literal
string.
