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

[eldenmoon]

• 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.'
