[Impeller] defer impeller context initialization onto the raster thread. (#167527) 
Attempt to speed up vulkan startup by ensuring vulkan driver
initialization happens on raster thread. Prev. we immediately
initialized the impeller::Context, unfortunately setting up the vulkan
context can take upwards of 100ms. This time is running on the platform
thread and blocking startup.

Instead, I attempt to hide/defer as much as possible what backend is
being used - this requires us to access the impeller context via a
shared_future in some cases instead of immediately knowing it is valid.

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
