fix(tvix/eval): thunk HasAttr expressions r/6216

HasAttrs was weird because with longer attribute paths it would
sometimes not turn out to be a thunk. If it was a thunk, it'd usually
still do some eval strictly which we'll want to avoid.

Verified against C++ Nix using a new test suite introduced in a later
CL.
