Store syntax aliases in serialized scoper infotable

[paulcadman]

This PR fixes an issue with importing syntax alias and using them from another module:

Say you have a module defining a syntax alias:

module SyntaxAlias;

import Stdlib.Prelude open;

syntax alias MyNat := Nat;

and another which imports / uses it:

module test073;

import SyntaxAlias open;

main : MyNat := 11;

The compiler crashed with the following error:

^?!): empty Fold
            CallStack (from HasCallStack):
              error, called at src/Lens/Micro.hs:711:28 in microlens-0.4.13.1-ARwI8t2x86cAxRs56XPcG1:Lens.Micro
              ^?!, called at src/Juvix/Compiler/Concrete/Translation/FromParsed/Analysis/Scoping.hs:565:29 in juvix-0.5.5-G7jC6MbkbsJGkMT9u4BkYQ:Juvix.Compiler.Concrete.Translation.FromParsed.Analysis.Scoping

We fix this by adding the aliases to the store's scoper info table and then use it to initialise the scoper state when scoping a module.
