Which issue does this PR close?
validate_string_viewand other utf8 validation #7014.Rationale for this change
Add simdutf8 for fast UTF-8 validation in arrow-data, arrow-array, arrow-row, and arrow-csv. A shared check_utf8() utility in arrow-data uses SIMD on the happy path and falls back to std::str::from_utf8 on error for detailed Utf8Error. The feature is default-enabled in the arrow umbrella crate.
What changes are included in this PR?
simd impl of utf8 instead of the standard lib method
Are these changes tested?
all tests passed
Are there any user-facing changes?
no
