Add a max size for normalize cache

This fixes #2484. Added a capacity to normalize cache. Default to 1024
and can be override by `quill.query.cacheDynamicMaxSize`.

Added a new dependency Google Guava to use its cache implementation. I
know it's better to avoid new dependency but Google Guava is a pretty
widely adopted library. It's cache implementation is widely tested. For
such a critical use case in quill, I think it's better to have a widely
tested implementation than reinventing the wheel.
