Disable vectorized `bitwise_invert` for boolean inputs

[ndgrigorian]

This PR proposes removing the sycl::vec overload of bitwise_invert for boolean inputs to fix unexpected behaviors.

Vectorized bitwise_invert on boolean inputs would corrupt the data in a subtle way. When casting this data to an integer data type, 255 would always be the result of casting true. This is likely related to operator! on sycl::vec returning -1 for true and expecting the output type to be a signed integer type.
