Automatic resolve multisampled resources in frame graph

[onox]

Automatic resolve multisampled resources if the resource was written as a FB attachment by blitting the framebuffer. If the resource was written as an image, then so automatic resolving should occur.

For example:

P1 -> R1 -> P2

R1 can be resolved by adding an extra pass that does nothing but a blit operation from the FB of P1 to P3:

P1 -> R1 [-> P3 -> R2] -> P2

The extra render pass should be able to blit mulitple resources (1 color and/or 1 depth and/or 1 stencil). The extra resource (R2) must have the same format.
