feat!: unified presets interface (#1045)

BREAKING CHANGE: Now all presets are exports preset config factory function. conventional-changelog-preset-loader now exports new loadPreset and createPresetLoader functions. If you are using presets indirectly, using preset name, no any changes in configuration needed, just upgrade packages to latest versions.
