Instrument impl library belonging to apexes

https://r.android.com/3094444 has removed instrumentation from the
implementation library of the java sdk library. However, given that the
top level java sdk library was not being instrumented before removing
the compilation action, there is no way to get the coverage data for the
java sdk library included in the mainline modules with the
aforementioned change.

As seen in b/340174053, instrumenting all impl libraries by default
may lead to double instrumentation execution time error in some edge
cases (especially with make to soong dependency).

Given the above two conditions, this change allows instrumentation for
the implementation library of the java sdk library that belongs to
apex(es).
