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

We have implemented support for StringViewArray in arrow-rs (see #6163 and https://www.influxdata.com/blog/faster-queries-with-stringview-part-one-influxdb/ ) and to take full advantage of it, kernels that operate on strings (StringArray and LargeStringArray) need to be updated with specialized implementations that can

Natively operate on StringViewArray without having to covert first to StringArray
(Potentially) take advantage of the new string view layout

regexp_match is one of these functions that does not have native StringViewArray support yet

Describe the solution you'd like

  1. Implement regexp_match for StringViewArray
  2. Implement regexp_array_match for StringViewArray
  3. Implement regexp_scalar_match for StringViewArray
  4. Tests for same

Describe alternatives you've considered
