[CK][CK TILE] Dispatcher kernel selection heuristic for
 grouped conv (#6327)

## Motivation
The ML heuristic in dispatcher does not support grouped-conv operator
yet. In this PR, the support for fwd, bdw-data, and bwd-weight
grouped-conv kernels have been added. A tile_engine utility has also
been added to compile and run any selected kernel configuration through
dispatcher infrastructure.

## Technical Details

1. Tile engine utility is added to benchmark each shape with all the
possible kernel+tile_size combinations here -
[https://github.com/ROCm/rocm-libraries/blob/users/yraparti/ck/dispatcher-grouped-conv-heuristics/projects/composablekernel/tile_engine/ops/grouped_conv/grouped_conv_full_benchmark.py](url)
2. New LGBM regressor models for grouped conv are added to models
directory. We have 3 separate models for fwd, bwd-data, and bwd-weights
[https://github.com/ROCm/rocm-libraries/tree/users/yraparti/ck/dispatcher-grouped-conv-heuristics/projects/composablekernel/dispatcher/heuristics/models](url)
3. Implemented lazy GPU initialization (dispatcher/python)
- **Issue**: ProcessPoolExecutor fork() + GPU context caused memory
access faults
- **Solution**: Mirror FMHA pattern - defer GPU initialization until
first run()
  - **Changes**:
- setup_multiple_grouped_conv_dispatchers() returns List[Path], not
loaded libs
    - GpuGroupedConvRunner.__init__() no longer calls ctypes.CDLL
    - Added _ensure_initialized() method for lazy GPU loading
    - GPU context created only on first run() call
  - **Benefit**: Parallel compilation now works without GPU conflicts
4. Addressed few miscellaneous issues such as:
  - Fixed BF16->FP16 naming bug in the dispatcher wrapper
- Added new tile sizes, and comp_v5 pipeline to the arch spec to expand
the kernel selection
- Added automatic padding support for unsupported shapes in dispatcher
runner
- Created a single source of truth between tile_engine and dispatcher
about the architecture and tile_size details
- Build a validation scripts to compare oracle_best vs ml_heuristic
comparison

## Test Plan

1. Validated fwd, bwd-data, and bwd-weight kernels with both known and
unseen data sets with up to 300 problems.
2. Ensured that test cases are added in both dispatcher and tile_engine
to validate the heuristic.

## Test Result
Results on Unseen shapes validated on gfx950
#### Forward Pass Model
- **Training Data**: 48,845 measurements across 1,372 unique problem
shapes
- **Validation Set**: 300 unseen problems from model crawler
- **Validation Performance** (vs. oracle):
  - Mean Efficiency: **93.05%**
  - Median Efficiency: **96.8%**
  - P10 Efficiency: **79.9%**

#### Backward Data Gradient (bwd_data) Model
- **Training Data**: 18,773 measurements across 891 unique problem
shapes
- **Validation Set**: 300 unseen problems from model crawler
- **Validation Performance** (vs. oracle):
  - Mean Efficiency: **93.8%**
  - Median Efficiency: **96.5%**
  - P10 Efficiency: **82.9%**

#### Backward Weight Gradient (bwd_weight) Model
- **Training Data**: 34,900 measurements across 1,508 unique problem
shapes
- **Validation Set**: 300 unseen problems from model crawler
- **Validation Performance** (vs. oracle):
  - Mean Efficiency: **96.1%**
  - Median Efficiency: **99.2%**
  - P10 Efficiency: **89.4%**

Extended synthetic training set for BWD_DATA targeting validation gaps.
Based on validation analysis:
- Low efficiency on small spatial + high channels (7x7, 14x14 with C/K >= 256)
- Low efficiency on moderate spatial + moderate channels (28x28, 32x32)
- Good efficiency on large spatial + small channels (already covered)
- CRITICAL: Add stride-2 with 3x3 filter (missing common downsampling pattern)
- CRITICAL: Add dilation support (zero training data exists)
- CRITICAL: Add 3D convolution support (infrastructure ready, zero data)
This set focuses on ~1500+ carefully selected problems covering weak areas + dilation + 3D.
