[Variant] Add `shred_variant` support for `LargeUtf8` and `LargeBinary` types

[sdf-jkl]

Is your feature request related to a problem or challenge? Please describe what you are trying to do.

Working on #9518 I noticed that shred_variant doesn't support LargeBinary and LargeUtf8 while VariantArray::try_new() supports both.

LargeUtf8 also just got unshred_variant support in #9515.

We should add shred_variant support for these types.

Describe the solution you'd like
