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.
