Sema: enhance is_non_err to be comptime more often

 * Sema: store the precomputed monomorphed_funcs hash inside Module.Fn.
   This is important because it may be accessed when resizing monomorphed_funcs
   while this Fn has already been added to the set, but does not have the
   owner_decl, comptime_args, or other fields populated yet.
 * Sema: in `analyzeIsNonErr`, take advantage of the AIR tag being
   `wrap_errunion_payload` to infer that `is_non_err` is comptime true
   without performing any error set resolution.
   - Also add some code to check for empty inferred error sets in this
     function. If necessary we do resolve the inferred error set.
 * Sema: queue full type resolution of payload type when
   `wrap_errunion_payload` AIR instruction is emitted. This ensures the
   backend may check the alignment of it.
 * Sema: resolveTypeFully now additionally resolves comptime-only
   status.

closes #11306
