Addressed Coverity issue about handling bools in floor_divide

[oleksandr-pavlyk]

Coverity flaged floor_divide functor for boolean input types.

114040 [Operands don't affect result] (static_checker_CONSTANT_EXPRESSION_RESULT)
The expression's value does not depend on the operands; often, this represents an inadvertent logic error.

In dpctl::​tensor::​kernels::​floor_divide::​FloorDivideFunctor<bool, bool, signed char>::​operator ()(bool const &, bool const &): An operation with non-constant operands that computes a result with constant value ([CWE-569](http://cwe.mitre.org/data/definitions/569.html))

Wrote dedicated simpler code for handling boolean inputs.
