Unwraps a scoped config value from a DomainConfig, AppConfig, or InfraConfig object, returning early if the value is not available.

This macro retrieves a config value for a given tileset or layout and automatically handles the error case. If the config value is not available, it returns a ChainableResult error with a formatted message. Otherwise, it unwraps the value and creates a local variable with the name specified by the config parameter.

Parameters

ptr	A pointer to a config object
config	The name of the config method to call and the resulting variable name
tileset	The tileset parameter to pass to the config method
return_type	The template parameter for ChainableResult in case of error
