Handle seenEmittedFiles which was not being set when emit of a file was complete (#33145)

Browse Source 
* Add test that fails because file is written multiple times
Reported from #33061

* Handle seenEmittedFiles which was not being set when emit of a file was complete.
It was issue only when errors are reported before emitting (which puts the files into pendingEmit that needs to check only in seenEmittedFiles)
If emit happens before semantic diagnostics query this issue is not repro, because the affected files come into play and those are being set correctly
Fixes #31398

* make baselining source map optional

* Handle emitDeclarationOnly in --build scenario

* Ensure we are using d.ts emit as signature even when --declarationMap is on (map files are emitted before d.ts)

* Move module specifiers to verifyTsBuildOutput

* implement create Hash to be default hashing plus data so we can verify it easily in baseline

* Remove failing baseline

* Accept correct baseline name
