📄 Description

Summary of the Pull Request

This commit introduces a copy constructor/operator for
_CONSOLE_API_MSG. The change is not trivial as the struct contains a
union of unnamed structs that cannot be copied using regular language
features. As such a copy operator using memcpy was implemented.
Additionally all access specifiers were removed, as those allow a C++
compiler to reorder struct members. This would break message passing.
This commit is a good opportunity to prevent such miscompilations
proactively.

Validation Steps Performed

  • Command prompts of WSL2 fish-shell and pwsh still work ✔️

Closes #10076
