Could you fix this, @hoffermei ? Currently, CIs complain on that.

If this is originated from ORC-1130, we need to backport this to branch-1.9 and branch-1.8. |

This PR aims to fix #1640 by resetting `BooleanRleEncoderImpl::current` and `BooleanRleEncoderImpl::bitsRemained` when suppress As #1640 suppress no null present stream leaves dirty data of BooleanRleEncoderImpl::current and BooleanRleEncoderImpl::bitsRemained, which will be flush to next stripe's present stream if it has some null values. I hava add a test testSuppressPresentStreamInPreStripe, which will construct a orc file with two stripe, the first stripe has no null value and seconds stripe has some null values. The constructed orc file writer have some dirty data in BooleanRleEncoderImpl for present stream. In the test I have add check for read ok and read result is same as write. Closes #1640 . Closes #1641 from hoffermei/present_supress_bugfix.
