Improve performance of casting StringView/BinaryView to DictionaryArray

[XiangpengHao]

Which issue does this PR close?

Closes #5861 . This pr should only be reviewed/merged after #5871 is merged.

Rationale for this change

Cast view types to dictionary arrays, the opposite of #5871

Note that casting was handled by pack_byte_to_dictionary:
https://github.com/XiangpengHao/arrow-rs/blob/dict-to-view/arrow-cast/src/cast/dictionary.rs#L307

But it takes two steps: Utf8View -> Utf8 -> Dictionary, which causes two copies.
This PR only do one copy (directly from Utf8View -> Dictionary<>)

What changes are included in this PR?

Are there any user-facing changes?

Thank you @XiangpengHao --

Since the rationale for these changes is performance, I think we should have benchmark results showing how much faster it is.

Thus, can you please make a PR with a banchmark (a single PR with benchmarks both for this change and the one in #5871)

Then we'll use the benchmarks to verify that this PR really does improve performance (I am sure it will, but we should double check)

I took the liberty of merging this PR up from main. Running performance benchmarks on it now

I measure a 30% performance improvement on this branch. Thank you @XiangpengHao

I guess it should. Are there any remaining items?
