Fix WGPU_SETTINGS_PRIO with trace_tracy

[beicause]

Objective

When profiling using trace_tracy and WGPU_SETTINGS_PRIO="webgpu" or "webgl2", bevy panics because timestamp query features are not enabled on the device.

Solution

Enable wgpu::Features::TIMESTAMP_QUERY | wgpu::Features::TIMESTAMP_QUERY_INSIDE_ENCODERS on the device when tracing-tracy enabled so that you can profile at webgpu/webgl2 limits.

Testing

WGPU_SETTINGS_PRIO="webgpu" cargo r --example bevymark --features trace_tracy

[beicause]

Actually this is unrealted to wasm build because trace_tracy (and required wgpu features) doesn't work on web at all. This is only for conveniently using the web's limits in profiling.
