refactor(tvix/eval): use im::Vector directly where possible

Browse source 
The conversion from im::Vector -> Vec is cheaper for NixList
construction (of course), so where possible we should make use of
that.

This updates most builtins dealing with lists to use Vector directly,
and marks the function constructing NixList from Vec as deprecated so
that we get appropriate warnings in places where it's still in use.

These places are currently inside of JSON serialisation logic which is
in flux right now, so lets leave them as-is until it's stabilised.
