[PR] [opt](table-function) Optimize explode with block fast path [doris]

eldenmoon opened a new pull request, #60348:
URL: https://github.com/apache/doris/pull/60348

   - Add a block fast path for explode-like table functions to expand contiguous nested ranges without per-row get_value()
   - Fall back to the original row-wise path when the nested range is non-contiguous or unsupported
   - Add/extend unit tests to cover fast path and fallback cases
   
   Test: ./run-be-ut.sh --run --filter='TableFunctionOperatorTest.*:UnnestTest.*'
