Settings: Add get_flags API for mapgen flags (mg_flags, mgv6_spflags, ...) (#9284) 

Unified flags handling in C++ and Lua Settings API
     -> Reading only, for now. Writing can be implemented later, if needed.
API function to read the currently active flags
     -> was impossible from Lua

* `default` is the value returned if `key` is not found.
* Returns `nil` if `key` is not found and `default` not specified.
* `get_np_group(key)`: returns a NoiseParams table
* `get_flags(key)`:
* Returns `{flag = true/false, ...}` according to the set flags.
* Is currently limited to mapgen flags `mg_flags` and mapgen-specific
flags like `mgv5_spflags`.
