Currently, `variant_get` only supports literal paths as the second argument.
Users may have columns containing paths which they would want to extract from
variants. This PR allows this functionality.
### Does this PR introduce _any_ user-facing change?
Yes, prior to this PR, `variant_get` did not have support for non-literal
paths.
### How was this patch tested?
Unit tests to make sure that:
1. The VariantGet/TryVariantGet expressions with non-literal paths has the
expected behavior regardless of codegen mode.
2. VariantGet expressions with non-literal paths do not get pushed down as
this functionality has not been implemented.
### Was this patch authored or co-authored using generative AI tooling?
No.
