Prevent storage reference to another reference

[turbolent]

Closes https://github.com/dapperlabs/cadence-internal/issues/235

Description

Based on #3398. Thanks for @dsainati1 for the initial investigation.

Nested references are not allowed.

The creation of an ephemeral reference, e.g. through a reference expression, already prevents this (NewUnmeteredEphemeralReferenceValue aborts with NestedReferenceError).

Also prevent storage references to references. Given that the target of a storage reference is a path and the value stored in the path may change, check the referenced value is not a reference value on each dereference, not just when the storage reference is created.
