This is duplicate of #92802

Started working on this:
When moving data_enhanced code into data plugin we need to make data plugin optionally depend on taskManager and security. There is no issues with taskManager, but there are cycles with security.:

• data -> security -> data. Security only uses dataViews, so can depend on dataViews directly.
• data -> security -> home - > data . Same home only uses dataViews, so can depend on dataViews directly.
• data -> security -> home -> customIntegrations -> presentationUtils -> data. I think we can break up customIntegrations -> presentationUtils. Break customIntegrations -> presentationUtil dependency  #121951

The pr that remove data_enhanced is here: #122075

It is blocked by flaky ci, the failure reason is unclear.
I isolated the flakiness here: #121955
It appears after commit that add security as optional dependency of data plugin

Summed up a blocker in #123720

WIP in #122075, currently blocked by #121951 due to tsconfig refs circular dependency
