Better approach to handle 'moduleName' in project level DSL

Now project level DSL only configures base part of module name, which
latter is enhanced by Kotlin compilation suffix. In this case
'KotlinCompilation.moduleName' is not used.

Additionally,
'KotlinJvmTask.moduleName' usage was deprecated in favor of
'compilerOptions.moduleName'. Though warning is only produced in case
project is using 'org.jetbrains.kotlin.jvm' or
'org.jetbrains.kotlin.android' plugins.

- 'moduleName' is always required to be non-null.
