Add support for non compiling scripting language

## What problem does this solve or what need does it fill?

Currently Bevy require to have on computer rustc compiler to be able compile and use game which user created.

## What solution would you like?

Adding new interpreted language will allow to run games without needing to compile anything.

Such language is really great to create fuzzers or tests

Engines like Godot or Unreal Engine have their own scripting languages GDScript and Unreal Verse(still WIP) which doesn't require compiling and works on almost any computer out of box.

Other engines use e.g. Python or Lua but this greatly increase its size since additional software must be present inside game engine to properly parse and execute code written in this languages
