Also make Caster object static constexpr in generic copy kernel as it is done in contig kernel.
Since convert_impl input argument is a reference, implement NumPy's interpretation of bool (underlying byte has any bits set in it) to override C++'s interpretation (underlying byte has the first bit set). To allow such an intepretation to work correctly bool arguments must be passed by reference, rather than by value. Passing by value creates a copy where C++ masks higher bits out.

This PR reverts changes from gh-2122 and fixes gh-2121 in
dpctl::tensor::type_utils::convert_implinstead.Doing so improves performance of conversion from boolean arrays by avoiding temporary allocation and the cost of launching a kernel implementing
not_equaloperation.The test for gh-2121 exists in
test_usm_ndarray_ctor.py::test_astype_gh_2121.A comment #2121 (comment) was left in #2121 to observe that C++ behaves differently than NumPy and that this was the cause for behavior reported in #2121.
