gpui_wgpu: Fix WGPU panic from unsupported atlas texture formats (#53808)

We were assuming that `Bgra8Unorm` always works, which was causing the
panic on configurations that don't support it ("wgpu-hal invariant was
violated: Requested feature is not available on this device")

This change makes a proper fallback to `Rgba8Unorm`. In the worst case,
if a device doesn't support that as well (highly unlikely), we return a
proper error instead of a panic.
