Rollup merge of #136886 - ehuss:remove-prelude-common, r=jhpratt

Remove the common prelude module

This fixes the issues described in #136102. Primarily, this resolves some issues with how the documentation for the prelude is generated:

- It avoids showing "unstable" for macros in the prelude that are actually stable.
- Avoids duplication of some pages due to the previous lack of `doc(no_inline)`.
- Makes the different edition preludes consistent, and sets a pattern that can be used by future editions.

We may need to rearrange these modules in the future if we decide to remove anything from the prelude again. If we do, I think we should look into a different solution that avoids the documentation problems.

Closes #136102
