[COFF] Rename the COFFShortExport::AliasTarget field. NFC. (#89039)
It turns out that the previous name is vaguely misleading.
When operating on a def file like "symbolname == dllname", that is
supposed to make an import library entry, that when the symbol
"symbolname" links against this, it imports the DLL symbol "dllname"
from the referenced DLL. This doesn't need to involve any alias, and it
doesn't need to imply that "dllname" is available on its own as a
separate symbol in the import library at all.
GNU dlltool implements import libraries in the form of "long import
library", where each member is a regular object file with section chunks
that compose the relevant .idata section pieces. There, this kind of
import renaming does not involve any form of aliases, but the right
.idata section just gets a different string than the symbol name.
