feat: removed the cache last generated commands, so they're one only one entity
feat: reworked the conversion from our cache to the compile_commands.json format
feat: unified the serialization and serialization entities. The intermediate ones used to clone data from the non-owned version of the cache has been deleted, and the SourceCommandLine now only works with owned data, so there's no need anymore to use those intermediate data mappers (that already was cloning from borrowed data)
