refactor(tvix/eval): Make `strict` an EvalMode enum r/8796

Refactor the `strict` boolean passed into evaluation at the top-level to
be a (two-variant, so far) EvalMode enum of Lazy and Strict.

This is more explicit than a boolean, and if we ever add more EvalModes
it's a simple extension of the enum.
