This is a partial revert of commits:
858657366f Remove support of disabling Jack.
3ae7861252 Remove javac support in host dex rules.
22313f2b2a Remove rules for building dex with dx
Test: builds
Change-Id: Ie12d743cbe978bdeb030910848b67f5945a4fec8
We removed code and variables related to running dx on classes.jar in
this change. Also removed target emma rules (but kept the emma rules for
host java libraries), for it's now done by Jack.
We still support to build classes.jar (and javalib.jar for static Java
libraries) using javac, because tools like javadoc need class files as
input.
Removed the obsolete install-dex-debug.

(cherry picked from commit b68c9a498d)

Set LOCAL_BUILT_MODULE of static java libraries when Jack is enabled
to classes.jack instead of javalib.jar.
This allows that running mm in those libraries will build classes.jack
instead of the jar.
