feat(scripting): add depends function in lua

[mcanais]

Description

Added cubos.depends() function to the lua api which allows to dynamically import the contents of a plugin (components, resources and relations) and return them as a table in lua.

Each of the contents is represented as a userdata (pointing to const reflection::Type*) with a metatable corresponding to its kind (either component, resource or relation).
