Use the same pak files for the Alloy and Chrome runtimes (see issue #2969)

Browse Source 
Chrome currently uses chrome_100_percent.pak, chrome_200_percent.pak,
resources.pak and locales/<locale>.pak files. This change adds CEF
resources to those existing pak files and updates the Alloy runtime to
use them instead of the previous CEF-specific pak files (cef.pak,
cef_100_percent.pak, cef_200_percent.pak, cef_extensions.pak,
devtools_resources.pak) which are no longer generated.

The addition of Chrome resources results in an ~16% (~4.1MB) increase in total
combined pak file size vs. the previous CEF-specific pak files. While a size
increase is not ideal for the Alloy runtime, it seems preferable to the
alternative of distributing separate (and partially duplicated) pak files for
each runtime, which would have added ~9.8MB to the total binary distribution
size.
