Remove support for saving a `Pointer` in the `EvaluationResult` since that was
unused. Add `stealAPValue()` which moves the `APValue` out of the
`EvaluationResult` to avoid a copy at the end of the evaluation.

Move the `APValue` into `EvaluationResult` instead.
For a large primitive array (`#embed` of the sqlite3 amalgamation), this
improves compile times by around 25%.

This reverts commit 9642aadf7064192164d1687378d28d6bda1978c9.
Since elem() only works on primitive arrays anyway, we don't have to do the
isArrayRoot() check at all.

Now that we don't have the PointeeStorage pointer anymore, it's simpler to
access the members of the anonymous union directly instead of using
asBlockPointer(), etc.

We need to use the base offset in both cases.
Also, add additional assertions to make sure we don't miss this case again.

When we get to this point, the pointer might _not_ be backed by a primitive
array, so the later code will fail.
