Add Support for Kotlin Ktor code gen

Is your feature request related to a problem? Please describe.

Kotlin the rising star in the Multiplatform sky needs to be part of Postman. Beside Android development the usage of Kotlin as primary programming language increases every day. More and more developers use Kotlin for backend or even Multiplatform software (Web, iOS, Native, Desktop etc.)
For this particular mission we should add Kotlin Ktor code generator.

Describe the solution you'd like

Similar to the current java okhttp code generator I would like to see a code generator for Kotlin Ktor.

Additional context

For better understanding whats the current state of the Kotlin ecosystem look here:

Kotlin Website
Ktor Website
Ktor Client Documentation

The Ktor HTTP client can be used in multiplatform projects and supports the following platforms:

JVM
Android
JavaScript
Native (iOS and desktop, including linuxX64, macosX64, mingwX64)

Start by examining the existing Java OkHttp code generator and the Ktor Client documentation linked in the issue. Determine how a Kotlin Ktor generator fits the repository's generator structure and supported targets. Done means adding a working generator that produces valid Ktor client code for the relevant request examples and integrating it with the existing generator set.
