[SE-0111] Propagate function reference kinds when building member references.

This helps when we end up re-typechecking an expression, which we seem
to be doing with 'lazy'. Specifically, it was causing type inference
for lazy variables to fail, but the same issue would have come up in
other contexts as well. Note that we also set function reference kinds
of DeclRefExprs and related in the process.
