[Intel-gfx] [PATCH] tests: Make it easy to tell if rendercopy is doing the right thing

[Damien Lespiau]

When dumping an .aub file, gem_render_linear_blit samples a texture to
write it in a render target 1:1.

When enabling new platforms, it's really handy to be able to see if you
are actually rendering to the target which is hard to see currently as
all the buffers are initialized with incrementing numbers and look very
much alike.

So, when dumping an .aub file for inspection, let's fill the destination
buffer with a constant color (0xff0000ff) and dump both src and dest bos
into bmp files.
