[Gradle] Add compiler options DSL for Kotlin targets

Restore compiler options DSL for all Kotlin targets. 'KotlinTarget'
interface does not provide any common way to configuring options - this
is the responsibility of related plugin extensions.

From the hierarchical standpoint of view target DSL overrides options
configured in the extension.
