Chris Bieneman 6e05c8dfc8 [DX] Create globals for DXContainer parts
DXContainer files have a handful of sections that need to be written.
This adds a pass to write the section data into IR globals, and writes
the shader flag data into a global.

The test cases here verify that the shader flags are correctly written
from the IR into the global and emitted to the DXContainer.

This change also fixes a bug in the MCDXContainerWriter, where the size
of the dxbc::ProgramHeader was not being included in the part offset
calcuations. This is verified to be working by the new testcases where
obj2yaml can properly dump part data for parts after the DXIL part.

Resolves issue #57742 (https://github.com/llvm/llvm-project/issues/57742)

Chris Bieneman 2af61e620e [DirectX] Add DirectX target object writer
This is the last piece to bring together writing DXContainer files
containing DXIL through the DirectX backend.

While this change only has one test, all of the tests under
llvm/test/tools/dxil-dis also exercise this code. With this change the
output object file type for the dxil target is now DXContainer. Each of
the existing tests will generate DXContainer files, and the dxil-dis
tests additionally verify that the DXContainers generated are
well-formed and can be parsed by the DirectXShaderCompiler tools.

Depends on D127153 and D127165

Chris Bieneman d401a99306 [DirectX] Embed DXIL in LLVM Module
At the end of the codegen pipeline for DXIL we will emit the DXIL into
a global variable in the Module annotated for the "DXIL" section.

This will be used by the MCDXContainerStreamer to emit the DXIL into a
DXContainer DXIL part.

Other parts of the DXContainer will be constructed similarly by
serializing their values into GlobalVariables.

This will allow DXIL to flow into DXContainers through the normal
MCStreamer flow used in the MC layer.

Depends on D122270
