Add boolean comparison to scalar kernels for less then, greater than

Is your feature request related to a problem or challenge? Please describe what you are trying to do.
We are implementing general purpose implementations of <, <=, >, and >= in DataFusion -- see apache/datafusion#1163

DataFusion uses different implementations if the left or right sides are scalar values vs if the left or right sides are both arrays.

Arrow has the lt_bool, lt_eq_bool, gt_bool, and gt_eq_bool kernels 🎉 added in #860 by @jimexist see docs for lt_bool

However, it does not have corresponding scalar variants, so I implemented simple versions in DataFusion to get the feature but they are not as optimized as they could be.

Describe the solution you'd like
Implement optimized kernels of lt_bool_scalar, lt_eq_bool_scalar gt_bool_scalar, gt_eq_bool_scalar

Simple versions are implemented in apache/datafusion#1163. The optimized versions should follow the pattern demonstrated in @Dandandan 's pr for eq_bool #844 -- namely doing the comparisons in 64-bit chunks when possible.
