[CK_TILE] Update Stream-K Reduction Strategy Enum
## Motivation
Currently, Stream-K has 3 reduction options: 1) atomics, 2) The
reduction described in the Stream-K paper, and 3) a tree reduction. The
reduction strategy described in the original Stream-K paper has the
starting workgroup of each tile sequentially accumulating partial
results of other contributing workgroups in the tile, which requires a
linear number of steps. Hence, for clarity, this works updates the
naming of the `StreamKReductionStrategy` enum members to better describe
the existing reduction strategy options.
## Technical Details
Prior to this change, the enum is as follows:
```cpp
enum StreamKReductionStrategy : uint32_t
{
Atomic = 0u,
Reduction = 1u,
TreeReduction = 2u
};
```
But, the distinction between `Reduction` and `TreeReduction` is not very
clear and has some redundancy.
Hence, the updated enum is as follows:
```cpp
enum StreamKReductionStrategy : uint32_t
{
Atomic = 0u,
Linear = 1u,
Tree = 2u
};
```
All references to `StreamKReductionStrategy` were updated to reflect
this change.
## Test Plan
No new functionality was added, so no new tests were added; I just
validated existing tests and examples.
## Test Result
All tests passed locally.

https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests.
* Stream-K smoke test config file generation
This change converts the stream-k smoke tests to use tile engine. Since
the m, n, and k values dependent on the CU count of a device, the
configs are generated during the Configuration Phase.
* Compute GEMM reference on GPU
* Remove redundant Stream-K tests
Removing redundant tests that are now run via tile engine.
* Fix relative and absolute tolerance calculation
This change updates the Stream-K tile engine interface to ensure that
num_wgs_per_tile is propaged and passed into the compare_results
function to calculate the rel and abs tolerance. Before, split-k was
used, which is incorrect for Stream-K since the split-k value is
always 1.
* Cleanup imports, types, and other misc items
This commit makes the following changes:
- Uses Typing module for nested type hints
- Uses quotes around cu_count_arg argument in generate_configs.cmake in
if statements
- Adds explicit include for tuple in test_gemm_streamk_simple.cpp
- Adds a type for the tiles argument in argparser to check argument
validity
* Use CU count as return value for better parsing
* Add reduction tests for bf16, fp8, and bf8
* Addition of Stream-K tests using Tile Engine
This change adds an implementation for generating Stream-K tests using Tile Engine.
This will generate various test executables for different combinations based on the
config files. This addition has simple tests running for bf16 and fp16, with both
atomic and reduction strategies and compv3 pipeline. The tests rely on the implementation
of Stream-K in Tile Engine.
* integrating addition of tree reduction and editing the README
* temporarily removing parallel and tree reduction from configs while bugs regarding them are being resolved
