  [llvm-lib][llvm-dlltool] Fix handling of invalid ARM64EC function names (#116250)

This is a follow-up to #115567. Emit an error for invalid function
names, similar to MSVC's `lib.exe` behavior.

Returning an error from `writeImportLibrary` exposed bugs in error
handling by its callers, which have been addressed in this patch.
