[cef] Stop using cros-toolchain
Previous cef and chromium recipes were using chromium's chrome os toolchain as it was the closest to what were needed to build chromium for target devices. However it contains additional settings and logic that may conflict with the cef recipe's compiler settings and change executable paths, so this fix changes to a custom toolchain that can be set according to AGL needs and preserve paths set in the recipe.
