As Gradle Groovy DSL does out-of-the box not allow working with
SAM-receiving functions in the same way as those accepting a Closure,
and, moreover, does not work with Kotlin default parameters, we need
to provide Groovy-friendly DSL functions along with Kotlin DSL functions
This commit adds those additional members for all of the newly
introduced MPP DSL members.
* Pull the `targets` and `presets` properties of the `kotlin` extension
up to an interface in `kotlin-gradle-plugin-api`
* Generate the code: we need type-safe statically-typed functions for
different target type, which seems to be only possible to achieve by
providing a function per preset.
* Place these functions in the top-level `kotlin` Gradle extension,
rather than extension functions for `kotlin.targets`:
- `kotlin.jvm { ... }` will work, while `kotlin.targets.jvm { ... }`
won't, the extension function needs to be somehow brought into scope
- reducing the nesting level by one seems to be a good move here
