Texture view leaks

[xiaopengli89]

Description
Related to #5595

500804e only clean up the suspected resources, weak pointers will leak if the texture never be dropped.

Repro steps
Minimal reproducible example:

use std::{thread, time::Duration};

fn main() {
    let ins = wgpu::Instance::default();
    let (_adp, dev, que) = pollster::block_on(async {
        let adp = ins.request_adapter(&<_>::default()).await?;
        let (dev, que) = adp.request_device(&<_>::default(), None).await.ok()?;
        Some((adp, dev, que))
    }).unwrap();
    let size = wgpu::Extent3d {
        width: 32,
        height: 32,
        depth_or_array_layers: 1,
    };
    let tex = dev.create_texture(&wgpu::TextureDescriptor {
        label: None,
        size,
        mip_level_count: 1,
        sample_count: 1,
        dimension: wgpu::TextureDimension::D2,
        format: wgpu::TextureFormat::R8Unorm,
        usage: wgpu::TextureUsages::TEXTURE_BINDING,
        view_formats: &[],
    });
    
    loop {
        let _view = tex.create_view(&<_>::default());
        que.submit(None);
        dev.poll(wgpu::Maintain::Wait);

        thread::sleep(Duration::from_secs_f32(1. / 60.));
    }
}

Expected vs observed behavior
Expected: process memory keeps stable
Observed: process memory grows without bound
