[ty] Do not re-export ide_support attributes from types

[sharkdp]

Summary

The types module currently re-exports a lot of functions and data types from types::ide_support. One of these is called Member, a name that is overloaded several times already. And I'd like to add one more Member struct soon. Making the whole ide_support module public seems cleaner to me, anyway.

Test Plan

Pure refactoring.
