Clean up EmbedderExternalViewEmbedder creation (#169962)
When creating an EmbedderExternalViewController, we were returning a
std::pair of the newly created instance and a bool, where the bool
indicated whether creation was successful or not. When true, creation
was unsuccessful and we should halt the engine launch. When false,
creation was successful and we should continue the engine launch.

Instead, we now return fml::StatusOr. When not StatusOr::ok(), we halt
engine launch, otherwise we continue.

No tests changed since this is a minor cleanup with no semantic change.

Flutter Engine

Setting up the Engine development environment

See here

gclient bootstrap

Flutter engine uses gclient to manage dependencies.

If you've already cloned the flutter repository:

  1. Copy one of the engine/scripts/*.gclient to the root folder as .gclient:
    1. Googlers: copy rbe.gclient to enable faster builds with RBE
    2. Everyone else: copy standard.gclient
  2. run gclient sync from the root folder
