[Impeller] acquire the gpu sync switch when flush stored GPU tasks. (#169596 )

Potential fix for https://github.com/flutter/flutter/issues/166668

See:

*
https://github.com/flutter/flutter/blob/master/engine/src/flutter/impeller/renderer/backend/metal/context_mtl.mm#L429
*
5d013c73ba/engine/src/flutter/fml/synchronization/sync_switch.cc (L41)

We don't hold the sync switch lock when we flush tasks. So if we start
flushing then immediately go to the background, then we might execute
while backgrounded.

`gclient` bootstrap

Flutter engine uses gclient to manage dependencies.

If you've already cloned the flutter repository:

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
run gclient sync from the root folder
