[gl] Fix 'inout' variable qualification + complex readback

- Can use variables with both input and output qualities
- Allow readback of complex structures. 3 phases:
   - host_pack_tmp_alloc: custom expression to allocate aligned
     temporaries for the output structs
   - host_pack: custom expression to pack into stream (losing
     alignment)
   - guest_unpack: custom expression to unpack into object on guest
     (regaining alignment)
