Create APEX variation only when needed

Create an APEX variation of a module only when it is either directly
included in an APEX or the dependency to the module demands that the
module should be included. For example, a non-static dependency to a
java library no longer creates an APEX variant of the library.

Bug: 146907857
Test: m (apex_test amended)
Test: cat out/soong/build.ninja | grep "Module:" | wc -l
reduced from 47132 to 45881
