Description

Updating the react-native-bridge's clean task to also delete the node_modules directory. This will help ensure that developers who are not familiar with js development have a good chance of recovering from a bad state using the gradle build.

In addition:

1. 8cda965 updates the message for the resetExtractedRNTools task to print during the execution phase instead of the configuration phase;
2. 0c81acb updates the name of the variable defining the (relative) path to the mobile gutenberg root to be more descriptive; and
3. db6769a updates the .editorconfig file to use spaces instead of tabs in .gradle, .java, .kt, and .xml files. For me Android Studio was picking up on the .edtorconfig file and, because that file specifies tabs as the default inside gutenberg/, Android Studio was overriding my settings and using tabs instead of spaces inside the gutenberg-mobile/gutenberg directory.

How has this been tested?

Cleaning

1. Within WPAndroid, ensure that your libs/gutenberg-mobile/node_modules and libs/gutenberg-mobile/gutenberg/node_modules directories are NOT empty. A dummy file is fine.
2. Ensure that WPAndroid's gradle.properties file has wp.BUILD_GUTENBERG_FROM_SOURCE set to false (or is missing that variable entirely).
3. From the WPAndroid root, run ./gradlew clean
4. Verify that the libs/gutenberg-mobile/node_modules and libs/gutenberg-mobile/gutenberg/node_modules directories no longer exist
5. From the WPAndroid root, run ./gradlew clean installWasabiDebug
6. Verify that you can load the gutenberg editor when running the generated apk
7. Verify that the libs/gutenberg-mobile/node_modules and libs/gutenberg-mobile/gutenberg/node_modules directories do not exist (confirms that the clean task does not interfere with the order of the tasks needed to generate the js bundle for android).

.editorconfig

Do the following for a (1) .gradle, (2) .java, (3) .kt, and (4) .XML file somewhere within packages/react-native-*/.

1. Enable EditorConfig support in Android Studio if not already enabled ( Settings → Editor → Code Style → Enable EditorConfig support )
2. Restart Android Studio and wait for it to fully restart so it has loaded .editorconfig (I don't actually know if a restart is necessary, but in my testing it was sufficient).
3. Add a non-empty line of code to one of the files specified above^.
4. Verify that the line is prefixed with tabs if using the previous .editorconfig file and prefixed with spaces if using the updated .editorconfig from this PR.
