feat(kotlin): support primitive array types

[codymikol]

Description

Currently the kotlin generator is unaware of the primitive array types. This adds all of them pulled from the official Arrays.ky file in the kotlin repo https://github.com/JetBrains/kotlin/blob/master/core/builtins/native/kotlin/Arrays.kt

Fixes #749

Commit Body
