[CK Tile] Async support pipeline V3

## Motivation

Optimize pipeline V3 for gfx950 by enabling buffer load to lds (async
pipeline)

## Technical Details

- Add `Async` bool to `Problem` struct to enable async pipeline in
existing one
- Add `static_move_ys` to load transpose. This generates offset in
assembly instructions saving registers
- Add `is_valid` to `async_get_vectorized_elements`. Before hard coded
to true. It allows to support padding
- Remove unnecessary restrictions to `is_a_load_tr` and `is_b_load_tr`
(wider use of lds load transpose on gfx950)
- Integrate async support in existing V3 pipeline (avoid pipelines
duplication)
- Create policy to support both async and default cases. This could be
used by any async pipeline (next steps)
- Define `wg_attr_num_access` separately for A and B. This allows to
optimize ds_read instruction width for cases when one matrix is
transposed and the other is not. Before in such cases, `ds_read_b64` was
used instead of `ds_read_b128`
- Add test for V3 async. Currently only supporting cases with A and B
having the same type

## Test Plan

New test `test_ck_tile_gemm_pipeline_compv3_async`

CK Tile Testing Guide

This document describes the test organization and available test targets for CK Tile operations.

Overview

CK Tile tests are organized with multiple levels of granularity to support different development workflows:

  1. Global test labels - Run tests across all operations
  2. Operation-specific umbrella targets - Run all tests for a specific operation
  3. Individual test executables - Run specific tests

Global Test Labels

These targets run tests across all CK operations (not just CK Tile):

ninja smoke

Run fast smoke tests (tests that complete within ~30 seconds on gfx90a).

ninja smoke

ninja regression

Run slower, more comprehensive regression tests.

ninja regression

ninja check

Run ALL available tests in the entire codebase.

ninja check

Operation-Specific Umbrella Targets

These targets allow you to run all tests for a specific CK Tile operation. This is useful when making changes to a particular operation and wanting to validate all related tests without running the entire test suite.

GEMM Operations

ck_tile_gemm_tests

Run all basic GEMM pipeline tests (memory, compute variants, persistent, etc.)

ninja ck_tile_gemm_tests

Test executables included:

  • test_ck_tile_gemm_pipeline_mem
  • test_ck_tile_gemm_pipeline_compv3
  • test_ck_tile_gemm_pipeline_compv4
  • test_ck_tile_gemm_pipeline_persistent
  • test_ck_tile_gemm_pipeline_compv6
  • test_ck_tile_gemm_pipeline_comp_async (gfx95 only)
  • test_ck_tile_gemm_pipeline_*_wmma variants (gfx11/gfx12 only)

ck_tile_gemm_block_scale_tests

Run all GEMM tests with block-scale quantization (AQuant, BQuant, ABQuant, etc.)

ninja ck_tile_gemm_block_scale_tests

Test executables included: 29 test executables covering:

  • AQuant tests (memory pipelines, base layouts, prefill, preshuffle, transpose)

./build/bin/test_ck_tile_gemm_pipeline_mem

Run a specific test through ctest

ctest -R test_ck_tile_gemm_pipeline_mem --output-on-failure
