refactor(tvix): always pass Bindings by ptr, use shared/unique_ptr r/1658
Value now carries a shared_ptr<Bindings>, and all Bindings constructors return a unique_ptr<Bindings>.

The test that wanted to compare two Bindings by putting them into Values has been modified to use the new Equal() method on Bindings (extracted from EvalState).
