test: Add umbrella test targets for CK Tile operations
 (#4301)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Proposed changes

Adds operation-specific umbrella test targets for CK Tile to enable
running all tests for a specific operation without running the entire
test suite. This improves the development workflow by allowing faster
iteration when working on specific operations.

## Motivation

Previously, developers working on CK Tile operations could only:
- Run individual test executables one at a time
- Run global labels (, , ) which test the entire codebase
- Build all tests for an operation but had no simple way to run them all

This made it cumbersome to validate changes to a specific operation
(e.g., GEMM quantization) without either running tests individually or
running the entire test suite.

### Documentation

- - Comprehensive testing guide with usage examples and implementation
details

## Usage Examples

# Run all GEMM tests with 256 parallel jobs
ninja -j256 ck_tile_gemm_tests

# Run all GEMM block scale (quantization) tests
ninja -j256 ck_tile_gemm_block_scale_tests

# Run all GEMM StreamK tests
ninja -j256 ck_tile_gemm_streamk_tests

Please put an into the boxes that apply. You can also fill these out
after creating the PR. If you're not sure, please don't hesitate to ask.

- [x] I have added tests relevant to the introduced functionality, and
the unit tests are passing locally
- [x] I have added the test to REGRESSION_TESTS list defined at the top
of CMakeLists.txt in tests/CMakeLists.txt, **IF** the test takes more
than 30 seconds to run.

with understanding the motivation
