[vm/kernel] Only create zone handles when necessary (e.g. in IR instructions, LocalVariable).

Summary:

When evaluating constants for direct inspection (and not for injection into the
FG), we store many intermediate values in ZoneHandles. This leaks memory, since
the only need for ZoneHandles is preserving constants which are referenced by
the FG.

Test Plan:

Existing coverage is sufficient since no functionality is changed.
