Colin Cross c48428a6bb Don't visit disabled modules with SOONG_COLLECT_JAVA_DEPS=true
Calling AndroidMk() on a disabled module may not be safe because
the module will not have had GenerateAndroidBuildActions() called
on it to initialize the data structures that AndroidMk() expects
to exist.  Check module.Enabled() before generating IDE info.

Fixes: 129089976
Test: SOONG_COLLECT_JAVA_DEPS=true m nothing
