[DirectX] Add boilerplate integration of objcopy for DXContainerObjectFile (#153079)
This pr implements the boiler plate required to use `llvm-objcopy` for
`DXContainer` object files.

It defines a minimal structure `object` to represent the `DXContainer`
header and the following parts.
This structure is a simple representation of the object data to allow
for simple modifications at the granularity of each part. It follows
similarily to how the respective `object`s are defined for `ELF`,
`wasm`, `XCOFF`, etc.

This is the first step to implement
https://github.com/llvm/llvm-project/issues/150275 and
https://github.com/llvm/llvm-project/issues/150277 as compiler actions
that invoke `llvm-objcopy` for functionality.
