Investigate usage of containers for Browser Script functionality

[its-a-feature]

Browser scripts in Mythic provide a lot of unique capabilities within the UI as developers are able to turn structured output into tables, file previews, and more. The need to do this in an abstract JavaScript way isn't great though.

See if there's a way to bring this functionality out of the browser and down into the Payload Type containers so that developers can create these in Python/Golang. This might introduce performance issues though as each request must go from:

browser -> Mythic server -> container -> Mythic -> browser -> render

This may or may not introduce lag, latency, or the inability to use browser scripts when containers are offline. The benefit is that people don't have to use JavaScript though.
