[Android] Fix proguard

Gyp supports only very limited ways of changing behavior based upon
CONFIGURATION_NAME. Particularly, it does not support the way that was
supposed to enable/disable use of proguard.

Instead of trying to switch behavior in gyp, instead pass
CONFIGURATION_NAME, proguard_enabled, and
proguard_enabled_dex_input_path to dex.py and switch the behavior
there.

This also extracts the dex actions into build/android/dex_action.gypi
and uses that for the actions in both build/java.gypi and
build/java_apk.gypi.
