WebGPURenderer: Handle OutOfMemory in Timestamp Tracking

[RenaudRohlinger]

Description

Add fallback for GPUOutOfMemoryError via device.pushErrorScope( 'out-of-memory' ) when creating timestamp query set. This prevents renderer breakage caused by failed sample buffer allocation.
Also added an error message suggesting users close other GPU-intensive tabs to enable timestamp measurements as it's in most case the issue triggering the error.

Before (crashing the renderer):

After (handle error, nothing breaks):
