[Blink] Fix bug in giving colorspace to CanvasResourceSwapChain

We use std::move(color_space) here, but we've already std::move'd the
color_space param into CanvasResourceProvider above. This effectively
means that CanvasResourceSwapChain would always get an SRGB colorspace.
This CL fixes the issue.

Note: The bug here landed in [1], which shipped in 133 [2].
