6a295eb7 - [JS/WebGPU] Creating devices with subgroup features enabled if possible (#21833)

[JS/WebGPU] Creating devices with subgroup features enabled if possible (#21833) This CL make WebGPU backend support subgroup features and thus allow using subgroup optimizations in the future. ### Description With this CL WebGPU backends will create devices with subgroups and subgroups-f16 features (both are under origin trial in Chrome) or chromium-experimental-subgroups feature enabled whenever available. ### Motivation and Context This CL would allow WebGPU operator shaders to use subgroup optimizations in the future, and might get some significant speedup with these optimization.
