Fix parallel rustc not being reproducible due to unstable sorts of items

[ywxt]

Currently, A tuple (DefId, SymbolName) is used to determine the order of items in the final binary. However DefId is expected as non-deterministic, which leads to some not reproducible issues under parallel compilation. (See #140425 (comment))

Theoretically, we don't need the sorting because the order of these items is already deterministic.

However, codegen tests reply on the same order of items between in binary and source.

So here we added a new option codegen-source-order to indicate whether sorting based on the order in source. For codegen tests, items are sorted according to the order in the source code, whereas in the normal path, no sorting is performed.

Specially, for codegen tests, in preparation for parallel compilation potentially being enabled by default in the future, we use Span replacing DefId to make the order deterministic.

But Items generated by a macro have a same span. We use DefPath to distinguish items generated by a macro.

At the cost of it, we have to manually sort items generated by macros for codegen tests.

This PR is purposed to fix #140425, but seemly works on #140413 too.

This behavior hasn't added into any test until we have a test suit for the parallel frontend. (See #143953)

I don't think the changes of diagnostic orders are expected.😅
