[WebGPU][CMake] Support executable target wgslc
https://bugs.webkit.org/show_bug.cgi?id=283111
Reviewed by Tadeu Zagallo.
Add ENABLE_WEBGPU CMake toggle, defaulted to off
Also port it to Clang on Linux x86-64:
- Don't assume building on Apple platform:
The notify framework is available only on Darwin.
- Don't assume __fp16 always exists. Use __Float16 instead.
Combined changes:
* Source/CMakeLists.txt: add WebGPU subdir if ENABLE_WEBGPU
* Source/WebGPU/CMakeLists.txt: Added.
* Source/WebGPU/WGSL/CMakeLists.txt: Added.
* Source/WebGPU/WGSL/ConstantValue.h:
When __fp16 is absent, fall back to _Float16 on non-Apple platforms.
_Float16 is in C++23, and commonly supported in Clang and GCC.
(WGSL::half::half):
(WGSL::ConstantValue::getHalf const):
* Source/WebGPU/WGSL/Metal/MetalCodeGenerator.cpp:
Don't use Darwin's notify API on non-Apple targets.
(WGSL::Metal::dumpMetalCodeIfNeeded):
* Source/cmake/OptionsJSCOnly.cmake: Turn off ENABLE_WEBGPU
* Source/cmake/WebKitFeatures.cmake:
Add ENABLE_WEBGPU toggle, defaulted off
