is it possible to defer uft8 validation pass the filters

### Is your feature request related to a problem or challenge?

for clickbench query 22 - 99% of the rows did not survive the filter
Today: decode → validate 100K rows → filter → 46 rows

i wonder if it possible to decode as BinaryView → filter → validate 46 rows → cast to StringView

even it is possible looks like its a lot of work to data fusion and arrow

Start by reproducing the ClickBench query 22 behavior described in the issue and trace the decode, UTF-8 validation, filtering, and StringView steps in DataFusion and its Arrow integration. Define done as demonstrating whether validation can be deferred safely and documenting the required scope and performance impact; the issue names no files or tests.
