Lua UDataTable and container ForEach fixes

[narknon]

Description

Adds early termination support to ForEach loops for all container types (TArray, TMap, TSet, UDataTable).

Previously, ForEach implementations called lua.call_function() with 0 expected return values, meaning callbacks could not signal early termination. This forced users to iterate through entire collections even when they found their target element.

This PR updates all ForEach implementations to:

1. Expect 1 return value from callbacks: lua.call_function(params, 1)
2. Check if the return value is boolean true to break the loop
3. Properly clean up the Lua stack for non-breaking iterations

The implementation follows the pattern already established by UEnum::ForEachName.

Example usage:

-- Stop iterating as soon as target is found
dataTable:ForEachRow(function(rowName, rowData)
    if rowName == "TargetRow" then
        -- Process the target
        targetData = rowData
        return true  -- Break out of the loop
    end
end)
