To be able to reference same dynamic feedback Lua script in multiple mappings

Discussed in #1219

This would look like the same implementation for reusing Lua scripts across multiple MIDI script sources introduced in 2.16.0, just for dynamic feedback Lua scripts in this case thanks.

Implemented in those commits. Accidentally associated with #1219 (the discussion) instead of the issue.

Test import:

{
    kind = "MainCompartment",
    version = "2.16.9",
    value = {
        mappings = {
            {
                id = "xZgKK432NHTMRxJsGE3l3",
                name = "1",
                source = {
                    kind = "Virtual",
                    id = 0,
                },
                glue = {
                    step_size_interval = {0.01, 0.05},
                    step_factor_interval = {1, 5},
                    feedback = {
                        kind = "Dynamic",
                        script = [[
local compartment = require("compartment")
return {
    feedback_event = {
        value = compartment.text
    }
}]],
                    },
                },
                target = {
                    kind = "Dummy",
                },
            },
        },
        common_lua = "return { text = \'hello world\' }",
    },
}

Enabling virtual feedback logging will show that it uses the text provided by the common compartment Lua.
