Hide Kotlin from CommentLanguageInjector as it only can insert simple
injection. Process injection by commented strings on our own.

 #KT-6610 In Progress

Place KotlinLanguageInject before TemporaryPlacesInjector

TemporaryPlacesInjector injects languages as a single place while we
need to distinguish interpolated and non-interpolated strings. Bad
ordering leads to inconsistent behaviour in temporary injection and
injection with annotations and comments.

E.g. "kotlinc foo.kt test/Bar.java" will compile foo.kt, and
declarations from Bar.java will be accessible to Kotlin code in foo.kt.

The change in AbstractTopLevelMembersInvocationTest is needed because an
incorrect configuration was created in that test where a library jar was
also a Java source root (the compiler is never configured this way in
production), which led to an exception in
JavaCoreProjectEnvironment#addSourcesToClasspath

Now we cannot simply remove introduced API because of bootstrap problems
