Eelco Dolstra 8c0590fa32 Never update values after setting the type
Thunks are now overwritten by a helper function
`Value::finishValue(newType, payload)` (where `payload` is the
original anonymous union inside `Value`). This helps to ensure we
never update a value elsewhere, since that would be incompatible with
parallel evaluation (i.e. after a value has transitioned from being a
thunk to being a non-thunk, it should be immutable).

There were two places where this happened: `Value::mkString()` and
`ExprAttrs::eval()`.

This PR also adds a bunch of accessor functions for value contents,
like `Value::integer()` to access the integer field in the union.
