Backends: WebGPU: use integer framebuffer size for viewport

Browse Source 
wgpuRenderPassEncoderSetViewport was passed FramebufferScale * DisplaySize in float, which can round one ULP above the render target size during resizing and trigger a wgpu validation error. Cast to int so the viewport stays inside the target.

Fixes #8628.
