[AllOpen] Reorganize module structure of AllOpen plugin

This scheme will be common for all compiler plugins with K1 and K2 support:
- `plugin-common` contains classes shared with K1 and K2 implementations (if any)
- `plugin-k1` contains implementation for K1 compiler
- `plugin-k2` contains implementation for K2 compiler
- `plugin-backend` contains implementation for backend extensions (if any)
- `plugin-cli` is module for registration of plugin in CLI compiler
- `plugin` is a root module with tests and all submodules embedded

This structure is needed to distinguish parts related to different frontends,
  which is needed for proper dependencies settings for Kotlin IDE plugins
