Due to a bug in the WebGPU emscripten bindings, the Dawn backend was only mapping 0-size region of a GPU buffer when invoking wgpu::Buffer::MapAsync. To map the entire buffer, we now call it with wgpu::kWholeMapSize. Note that due to the same Emscripten bug, wgpu::Buffer::GetMappedRange must be invoked with "size = 0" to obtaine the entire mapped range. This inconsistency was the root cause for the mapping failures described in skia:13266. Also removed the workaround in the webgpu-bazel demo and made the demo default to rendering a runtime effect because it's cooler.
