Subject: Add implementation for 'uploadTextureData' in metal (#6443)

Close issue: #6386.

- Implement uploadTextureData in metal
- Fix a bug in 'copyTextureToBuffer' in metal
    The last parameter for Metal::copyFromTexture is the
    'destinationBytesPerImage', but previous implementation
    fill in the destination size which is wrong in 3-D texture.
