[feature] Release without scripting support plugin to reduce bundle size

[narinishi]

Describe your idea

The inclusion of Kotlin in 1.5.0 has increased the file size of the main jar significantly. Please consider offering a variant without Kotlin.

@narinishi I plan to move scripting support plugin to external repo once API for UI customization allows doing so.
This should reduce the size of jadx bundle by ~60MB (most of this size is Kotlin compiler jar)
