1150423 - [System] expose device type to system app

Status: RESOLVED FIXED

Description

[John Hu [:johnhu][:johu][:醬糊小弟]]

To enable multiple device type in one system app, we should expose device type to system app. The following is our plan:

1. Create a FeatureDetector module which wraps feature detections functions, like navigator.getFeature(), document.implementation.hasFeature(xxx, xxx) and device type.
2. use system app's build script to expose __DEVICE_TYPE to window object
3. register FeatureDetector's deviceType to service.

BTW, please modify the navigator.getFeature used by InputWindowManager[1] to FeatureDetector

Alive, this patch introduce FeatureDetector to system app and exposes device type/device memory to service, would you review changes in system app? thanks!

Ricky, we tend to replace some variable in build time, and I add `matchFileContentInZip` to helper function for build integration test, would you review changes in build system part? thanks!
