Although the previous code of computing JVM internal name from a Class
instance was shorter, it led to unnecessary creation of array types,
which is less performant and makes configuration of kotlin-reflect for
GraalVM native-image more verbose.
Unfortunately I didn't succeed in writing a test for this, since
`Array.newInstance` calls a native method which doesn't record any trace
of it being called in the class loader: the resulting array type never
goes through findClass/loadClass, and is not visible via
findLoadedClass.

This is needed to provide ability for declaring new implementations of
test generators, based on existing infrastructure, which won't add
dependency on :compiler:tests-common
Also this commit removes implicit dependency on :compiler:tests-common
from :compiler:tests-common-new
The main change here is that when kotlin-reflect is being run under Java
9+, we use another implementation of BuiltInsResourceLoader (see
libraries/reflect/api/src/java9) which loads .kotlin_builtins files from
the java.lang.Module instance of kotlin-stdlib, instead of the class
loader of kotlin-reflect, which may not have access to those resources.
If the application is being run in the old (classpath) mode, that Module
represents the unnamed module, which contains everything on the
classpath, and everything works as before. But if it's being run in the
modular mode, that Module instance is an encapsulated module for
kotlin-stdlib classes and resources, exactly where .kotlin_builtins
files are located.
This fixes a regression in 1.4.0. Prior to 1.4, kotlin-reflect and
kotlin-stdlib were not named modules (see KT-21266) and were loaded as
_automatic_ modules even if the application was run in the modular mode.
Apparently, they shared the same class loader in that case and looking
up .kotlin_builtins resources worked.
This change was supposed to go alongside
828cc6dbf3, but was overlooked because
adding module-info to standard libraries was postponed at that point.
Also slightly refactor Java9ModulesIntegrationTest to simplify running
compiled code, and add a smoke test on using kotlin-reflect in modular
mode.

Otherwise this brings incompatibility between kotlin-reflect 1.3.70+ and
kotlin-stdlib 1.3.60-.
