[Variant] Impl PartialEq for VariantObject #7943

[alamb]

Is your feature request related to a problem or challenge? Please describe what you are trying to do.
According to the spec, field values are not required to be in the same order as the field IDs, to enable flexibility when constructing Variant values.

Describe the solution you'd like
Instead of comparing the raw bytes of 2 variant objects, this implementation recursively checks whether the field values are equal -- regardless of their order

Describe alternatives you've considered
