Fix patch for rocm6.3 (#793)

The header for ROCM 6.3.4 is not compatible with PyTorch 2.7.1's CMakeFind module's regex and we need to patch it post-download.

Additionally, an old patch is not useful anymore and has been removed.

 - Modernized typing syntax to use Python 3.10+ standards, replacing
   `Union[X, Y]` with `X | Y`, `Optional[X]` with `X | None`, and generic
   collections (`List[X]` → `list[X]`, `Dict[X, Y]` → `dict[X, Y]`, etc.).
