[RFC PATCH v3 1/9] libcamera: process: Disable copy/move

[Kieran Bingham]

Quoting Barnabás Pőcze (2025-03-25 18:08:13)
> A `Process` object has address identity because a pointer
> to it is stored inside the `ProcessManager`. However, copy/move
> special methods are still generated by the compiler. So disable
> them to avoid potential issues and confusion.
