fix(config-loader): enhance config-loader results

[azu]

This is breaking change, but @textlint/config-loader is internal use.

Changes

moduleName should be package's name

Previously, moduleName is a file path.

            {
                "type": "RuleInPreset",
                "ruleId": "abc/c",
                "options": false,
                "filePath": "<MODULES_DIR>/textlint-rule-preset-abc/index.js",
-                "moduleName": "<MODULES_DIR>/textlint-rule-preset-abc",
+                "moduleName": "textlint-rule-preset-abc",
                "ruleKey": "c"
            }

Add type: "Plugin"

        "plugins": [
            {
+                "type": "Plugin",
                "pluginId": "custom",
                "plugin": {},
                "filePath": "<MODULES_DIR>/textlint-plugin-custom/index.js",
                "moduleName": "textlint-plugin-custom"
            }
        ],

Add inputModuleName: string

Previously, the input module name is not defined in results.
In some usecase, a user want to map input to result.

For this usecase, the user can use inputModuleName <-> moduleName

• Isn't it possible to enable & disable specific preset by merge-config? editor#87

This is an example of ruleId and inputModuleName.
