[Android] Fixed calling extensionManager's onPause() and onResume() at wrong places

Call extensionManager's activity life cycle related codes in
onActivityStateChange. For now its onPause() is called with
ActivityState.STOPPED and onResume() is called with
ActivityState.STARTED, which are wrong.

[Android] XWalkViewInternal refactor
DEPS.xwalk: Move to 38.0.2114.2.

blink-crosswalk and chromium-crosswalk have been rebased (some patches
in the latter had to be skipped)

v8-crosswalk is vanilla from upstream, with no patches from our side
applied yet.

ozone-wayland is still tracking M37 and is likely to be broken.
Disable SIMD support while v8-crosswalk is not rebased.
