Support using simdutf8 for `validate_string_view` and other utf8 validation

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

We have some different sources were `std::str::from_utf8` is used for utf8 validation, such as `validate_string_view`.
We can speed it up by supporting `simdutf8` as well here.

**Describe the solution you'd like**

Similar for https://github.com/apache/arrow-rs/pull/6668 , optionally switch to using `simdutf8` instead.

**Describe alternatives you've considered**

**Additional context**

Start at the `validate_string_view` entry point and inspect the other uses of `std::str::from_utf8` for UTF-8 validation. Read the approach in apache/arrow-rs#6668 before deciding where `simdutf8` can be used. Done means the relevant validation paths support the faster validator while preserving existing validation behavior.
