Workaround DPCTL Level Zero issue (#242)

The static linking of the Level Zero loader into the Level Zero adapter
in intel/llvm#17104 causes DPCTL's logic to
detect the name of the Level Zero loader library to fail:
IntelPython/dpctl#2022

This in turn causes the creation of a SYCL `kernel_bundle` from SPIR-V
in the Python interface to fail and leads to CI failures on unrelated
branches.

This PR brings a workaround for this issue, by using a CMake fix for
DPCTL.
