Vulkan: Fixed capture buffer size. (#3783)

Browse Source 
captureSize used m_width for the row count, but the swap-chain readback
copies m_height rows (capture() reports _size = height * pitch, and
ReadbackVK::pitch() is width * bpp/8). A backbuffer taller than wide
under-allocates the readback buffer and overruns it. Use m_height, which
matches the GL backend's width*height*4.
