This change refactors the parte parsing logic to operate on StringRefs
of the part data rather than starting from an offset and splicing down.
It also improves some of the error reporting around part layout.
Specifically, this code now reports a distinct error if there isn't
enough data in the buffer to store the part size and it reports an
error if the parts overlap.

This was done as a test for D137302 and it makes sense to push these changes

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.

This patch refactors some of the DXContainer Object and YAML code to
make it easier to add more part parsing.
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.

This patch adds support for parsing the DXIL part data into the
ObjectYAML tooling.
The DXIL part has additional headers describing the shader and bitcode
data and stores serialized bitcode after the headers.

DXContainer files are structured as parts. This patch adds support for

This patch begins adding DXContainer parsing support to libObject.
Following the pattern used by ELFFile my goal here is to write a
standalone DXContainer parser and later write an adapter interface to
support a subset of the ObjectFile interfaces so that we can add
limited objdump support. I will also be adding ObjectYAML support to
help drive testing of the object tools and MC-level object writers as
those come together.
DXContainer is a slightly odd format. It is arranged in "parts" that
are semantically similar to sections, but it doesn't support symbol
listing.
