[WebGPU] Reserve additional keywords to avoid WGSL identifier collisions
(#18960)
Compiling Qwen3.5 yielded WGSL of the following form: `var<storage,
read_write> storage : array<f32>;
`. This led to a 'cyclic dependency' error due to the identifier
collision. This PR reserves keywords such as storage to avoid parsing
errors.
