[SCS-MultiApi-Plugin][OpenApi] Improve the performance of the program by reducing the times of parsing the OpenApi file

[Rivarsal]

Currently, the OpenApi file is being processed at least 3 times: Once for the global Object and it´s parameters, once for the basic schemas and once for the components.

As a developer I would like to reduce the amount of times that it process the OpenApi file into 1.

For that, we would have to refactor the getListComponentObjects and processBasicSchemas into one Method that maps both items needed
