Provide physical dimensions to wgpu Device::create_texture_with_data (#19129)

# Objective

- Make errors in #19124 #13289 clearer, and opt for option 1. of
https://github.com/gfx-rs/wgpu/issues/7677

## Solution

Remove the round to block size `.physical_size(texture_format);`

Error message now becomes much clearer:
```
thread 'Compute Task Pool (5)' panicked at E:\r\wgpu\wgpu\src\backend\wgpu_core.rs:1423:26:
wgpu error: Validation Error

Caused by:
  In Device::create_texture
    Width 2050 is not a multiple of Bc7RgbaUnormSrgb's block width (4)
```

## Testing

- Tested using the repro in #19124
