[ROCm][CI] Bump rocm-preview wheels to August 5 and bring in amdsmi changes (#192813)

## Problem
Preview CI is still on the July 12 TheRock pin (`7.15.0a20260712`). The August 5 index is ROCm 10.1, and that layout ships `amdsmi` without packaging metadata. Two linear CE-loss cases time out on SDK 10.

## Changes
Bump preview wheels to `10.1.0a20260805`. Install metadata-free AMD SMI via a `.pth` file. Skip the two CE-loss timeouts when `torch.version.rocm` major is 10.

Origami compile tests are no longer skipped on this PR. [#193843](https://github.com/pytorch/pytorch/pull/193843) landed as `945cf5cee9e` and disables Origami for ROCm 10.0+, including a class-level skip of `TestOrigami` when SDK `>= (10, 0)`.

## Validation
Rebased onto current `main`. Restored `test/inductor/test_origami.py` to match `main`. `python3 -m py_compile` on `test/inductor/test_origami.py` and `test/test_nn.py`. `git diff --check origin/main`. Preview CI is retriggered after this push.
