As `cuBLAS` workspaces are already per-stream, there shouldn't be kernel execution overlap with `cuBLASLt` kernels.
This PR reuses `cuBLAS` workspaces for `cuBLASLt` for the following benefits:
+ caching (`cuBLAS` workspaces were already cached, so now we get that for `cuBLASLt`)
+ "free" workspace size bump for `cuBLASLt` `cuBLASLt` workspace sizes were previously smaller than those for `cuBLAS` by default which potentially hurts performance, and we encountered difficulty in increasing the size due to downstream OOMs , see also #120925
+ fixes behavior broken behavior with the memtracker; https://github.com/pytorch/pytorch/pull/139442 attempted to handle peaky allocation behavior that broke memtracker equivalence tests but it didn't seem to fully work, here the cached/reused `cuBLAS` workspace seems to fix it
+ one environment variable to rule them all: `CUBLAS_WORKSPACE_CONFIG` applies directly to `cuBLASLt` without a confusing `CUBLASLT_WORKSPACE_SIZE` that users would also need to consider

Torchbench of timm lcnet_050 model fails on accuracy in case of `--frezing` `--inference` `--bfloat16`
`res_error==0.12`
If to turn off convolution inductor constant folding - `res_error==0.016`
`float16 error ~ 0.00669`
`float16 without conv folding ~ 0.0018`
convolution folding results in increase of error almost at one order of magnitude.
I think we should revisit and try to do something to improve the accuracy for conv folding.
E.g. For example doing conv folding at compilation time with float64?
At the moment I am adding counters to identify if convolution folding happened, and in case of bfloat16 and conv_folding - increase multiplier to the max level (10) to pass accuracy test.

Fixes https://github.com/pytorch/pytorch/issues/144772
The eager warmup runs causes the model to change state so that later when we export it, the model is different than when we export it directly out of box. For some reason exporting the model with the changed state causes issues but exporting the inital model is ok. This is the reason why the accuracy checks pass but the performance check fails when exporting.

I discovered this issue when trying to search for the accuracy results on the database and couldn't find any. It turns out that the results is there on the JSON file, for example `"metric": {"name": "accuracy", "benchmark_values": ["pass_due_to_skip"]}`, but inserting them into the database fails because benchmark values is a list of strings here while the expectation is that it's a list of numbers.
ClickHouse doesn't support mix types atm. It has a Variant type https://clickhouse.com/docs/en/sql-reference/data-types/variant, but this isn't recommended by CH team themselves. So, the remaining option is to store this in the `extra_info` field. This field is a dictionary, so it can goes there.

Summary:
To facilitate PSS-2 upgrade, this uses `ndt.NDArray` instead of `nd.ndarray` in type annotations. In Numpy-1.19 (PSS-1) it's an alias to `nd.ndarray` -- a noop.
In Numpy-1.24, `ndt.NDArray` a proper generic type, and without this change uses of `nd.ndarray` generate this Pyre type error:
```counterexample
Invalid type parameters [24]: Generic type `np.ndarray` expects 2 type parameters.
```

Pull Request resolved: https://github.com/pytorch/pytorch/pull/135960
Approved by: https://github.com/ezyang
Previously we were accomodating `torch._dynamo.mark_dynamic()` for export's dynamic shapes. Here we clean things up and ignore it, requiring users to specify an export input for `dynamic_shapes`.
Note: there's 4 decorators relevant to export, `mark_dynamic, maybe_mark_dynamic, mark_static, mark_unbacked`. User calls that involve export have only been `mark_dynamic()`, and we use `maybe_mark_dynamic` under the hood for `Dim.AUTO`, but we could start using others. One reason I decided to not warn and just silently ignore is these decorators cause the tensors to carry dynamic info, and it'll be hard to tell whether the markers are from export or user calls when re-exporting with the same inputs.

Summary:
By default, performance tests (speedup experiments) will run the baseline and test backend alternately.
However, this does not work for the torchao backend, which will change the model in-place, therefore the baseline run will also run with torchao backend since the model has already been quantized.
Add a new experiment "latency_experiment" to run performance tests non-alternately (first run baseline for a few iterations, then run the test backend).
other changes:
need to add torch.compiler.cudagraph_mark_step_begin() to avoid the
slowdown from # Unable to hit fast path of CUDAGraphs because of pending, uninvoked backwards
