android: Add support for html-packaged trace files to adb_profile_chrome
Add support for html-packaged trace files to adb_profile_chrome. The --html option will cause the trace file to be serialized into an html file that contains a snapshot of the Trace Viewer from the Chromium source tree. The resulting file has no other dependencies and therefore does not require a specific version of Chrome for viewing. This patch also adds the --view option for automatically opening the written trace file in a browser.
