Provide inspection and quickfixes for usages of static fields which will be no longer accessible in future versions

For this inspection three kinds of fixes are potentially available:
- Add 'const' modifier to kotlin property
- Add '@JvmField' annotation to kotlin property
- Change field reference to getter invocation

In case user chooses to 'cleanup code', these fixes are prioritized in this order
