Pyarrow: convert from DataType(string_view) to DataType(string)

Describe the usage question you have. Please include as many useful details as possible.

Hi, is there a way to cast a string_view array into a string array in Pyarrow?

I find that the string type is better supported, e.g. pc.count_distinct() works on a string array, but not a string_view array. It is also easier to interface with other libraries, since the string type is better supported in older versions.

Hi @kevinli1993, thank you for opening an issue!
There is an open issue that tracks progress of adding basic functionality to the new string view type (first in C++): #39634.

I suggest we follow the status of the linked issue and close this one.

That's perfect, thank you @AlenkaF for the pointer!
