anv/copy: Fix copying Images from Buffers with larger dimensions

This function previously assumed that the Buffer and Image had matching
dimensions. However, it is possible to copy from a Buffer with larger
dimensions than the Image. Modify the copy function to enable this.

v2: Use ternary instead of MAX for setting bufferExtent (Jason Ekstrand)
