Revert "[DebugInfo] Fix handling of @_originallyDefinedIn types"

[compnerd]

Reverts #78104

This is potentially breaking the round trip of symbol decoration.

@swift-ci please smoke test

@compnerd do you know which type is triggering the assertion failure?

[augusto2112]

There's no way to do the round trip when the type is annotated with @_originallyDefinedIn. I added some code to skip the round tripping for types affected by that attribute, but maybe I missed some cases.

$s11SwiftFormat24DocumentationCommentTextV13extractedFromACSg08CompilerA6Syntax6TriviaV_tcfc4LineL_VD is one of the two that we are seeing.

[augusto2112]

What project are you compiling? I don't see any @_originallyDefinedIn in swift-format or swift-syntax. Would you mind posting the entire error?

Reverting this PR seems to fix this issue: #78326 CC @augusto2112

[augusto2112]

I was able to reproduce it, let me work on a fix

[compnerd]

@augusto2112 can we revert the change if you cannot get the fix in before the freeze tonight?

[augusto2112]

@compnerd sure, I have a fix here: #78328

[augusto2112]

@compnerd in case mine fails in some other unexpected way you can open a PR reverting ce1a9d565f537f81b3d40e67666c91e9cc178938 and 15bb8ecccd8b371b9b33a876d8b04e8f8aa42eea on llvm-project, and cross testing with this one, to get it ready to merge just in case.
