Issue number: The resource linking is broken in IDE when custom_package is not set

Description of this change

As described in the issue: If the custom_package = "com.myPackage", is not set when defining a kt_android_library, and if the BUILD file is under the root of your project dir, the rules_kotlin or rules_android will pass a null value to init the IntelljiInfo. This will cause the resource link/preview not working in the IDE.

This change parse the packageName defined in the AndroidManifest.xml when the passed over javaPackage name is null. And use it as the resource package.

After the fix the IDE resource preview worked as expected. And when clicking on the resource from Kotlin code it will link to the resource xml definition, instead of the generated Int.

Thanks @ivyspirit! The change looks good to me, we are currently trying to move the code for the AS plugin outside of this repository and we cannot accept changes to it at the moment. I will try to import this change once the other repository is ready.
