Revert "Still run TritonBundler with BundledAOTAutogradCache, save autotune results (#158048)"

This reverts commit 8e57cdb746b4ab28865fdf01532f87b0d21700e9.

Reverted https://github.com/pytorch/pytorch/pull/158048 on behalf of https://github.com/jeffdaily due to rocm failures due to unit test introduced in this PR, but no pre-merge signal available ([comment](https://github.com/pytorch/pytorch/pull/158048#issuecomment-3098746624))
