Lei Wang c8fc0cbbcd [Backend][WebGPU] Support WebGPU WGSL code generation (#86)
* bump version into v0.1.0

* [Enhancement] Add custom develop command for editable installs and update .gitignore

* [Documentation] Update README to include system dependencies installation instructions

* [Build] Update setup.py to support library file copying for both release and develop modes

* [Build] Refactor library file copying logic in setup.py

* [Documentation] Remove unnecessary install section header in Installation.md

* [Build] Add tox configuration and local distribution script for multi-Python version support

* [Build] Improve git submodule update function with better error handling

* [Build] Update LLVM configuration path in ROCm installation script

* [Build] Add .tox/ to .gitignore for tox testing environment

* [Build] Add support for TVM prebuild path configuration in CMakeLists.txt

* [Cleanup] Remove unused TVM runtime error codes header

* [Cleanup] Fix TVM grid constant type reference in CUDA module

* [Cleanup] Remove unused customized_code function from IR module

* [Feature] Add TileLang thread synchronization and storage access analysis passes

* [Build] Reorder DLL search path directories for more flexible library loading

* [Refactor] Improve thread synchronization and library path handling

- Rename ThreadSync and TileLangThreadSync functions in C++ code
- Update Python docstring for ThreadSync with more detailed description
- Reorder library path detection in tilelang environment setup
- Minor comment and code cleanup in CUDA and warp specialization modules

* [Refactor] Improve thread synchronization code style and formatting

- Standardize pointer type spacing in storage_access.h and storage_access.cc
- Update whitespace and indentation in thread_storage_sync.cc
- Reorder include statements in thread_partial_sync.cc
- Minor code formatting improvements across thread synchronization files

* [Refactor] Fix global function registration for ThreadSync

- Correct global function registration to use ThreadSync instead of TileLangThreadSync
- Update TVM global registration to match recent refactoring efforts

* [Refactor] Simplify ThreadSync global function registration

- Remove unnecessary whitespace in global function registration
- Compact the TVM global registration line for ThreadSync

* [Feature] Add WebGPU code generation support in TileLang

- Implement WebGPU code generator (codegen_webgpu.cc and codegen_webgpu.h)
- Add WebGPU target support in lower.py and target.py
- Update CMakeLists.txt to include WebGPU codegen source files
- Introduce WebGPU-specific code generation for WGSL shader language

* [Refactor] Improve WebGPU code generation formatting and readability

- Enhance code formatting in codegen_webgpu.cc and codegen_webgpu.h
- Standardize pointer type spacing and indentation
- Improve line breaks and reduce line length for better readability
- Minor code style improvements in WebGPU code generation

* [Test] Add WebGPU matrix multiplication code generation test

- Implement test_webgpu_codegen.py for WebGPU matrix multiplication
- Add assert_gemm_codegen function to validate WebGPU code generation
- Include basic matrix multiplication kernel test case

* Update README with WebGPU codegen support announcement
