Prevent overflow with skip_rows in ORC and Parquet readers

[vuule]

Description

Use int64_t for skip_rows since source or combined sources can have more than two billion rows, and we should be able to read a range of rows even in that case.
Store num_rows as std::optional, instead of using special value (-1).
Reuse code with error-prone logic between ORC and Parquet.
Added unit tests for the tricky code above.
Converted inout select_stripes parameters to input params + return values.
