To migrate the default compilation over to using
"core platform api" stubs we need to make the "before"
state as close to the "after" state as possible.
The stubs will include all "core libraries" so it
makes sense to include those that contribute to the
"core platform api": okhttp, bouncycastle and conscrypt.
(apache-xml is not included because it doesn't contribute
to the core platform API).
After this change all explicit dependencies to okhttp,
bouncycastle and conscrypt in situations where the
default boot classpath is used can be removed.
A knock-on of this change is that the conscrypt, bouncycastle
and okhttp targets need to be adjusted to explicitly
depend on core-oj / core-libart with no_standard_libs: true
to avoid a cycle.
