Previously WebEngine was falling back to SW compositing after 3
GPU process crashes. This is not desirable when Vulkan is enabled
because it may mask other issues. Also not all features work correctly
with SW compositing (e.g. it's not compatible with HW video decoder).

Also added --disable-software-rasterizer to disable SwiftShader as
we should never need to use it on Fuchsia.
