Adds support for lowering and in `UpdateAsyncWaitCnt`. Note that on `gfx1250` async_loads use `asynccnt` which is separate from register and TDM loads so they can finish out of order. This means register and tdm loads should be ignored by `UpdateAsyncWaitCnt` and no performance remark for the former compared to `GFX9`. Intrinsics will be replaced by ROCDL ops once we bumped LLVM.
