Refactor ABI options as part of HIR function qualifiers

The AST has an ABI string as part of the function qualifiers, this was the
same in the HIR as it was initially a copy-paste. This patch changes the
HIR function qualifiers to have an enum of ABI options, during HIR lowering
the enum is setup and if an unknown ABI option is specified an error is
emitted.
