[SYCL][LIT] Mark spec const LIT as pass (#1875)

The spec_const LIT tests start to pass for Intel CPU and GPU devices
with the Intel OpenCL GPU driver 20.19.16754.

Duplicate the test for accelerators, e.g., FPGA, and only fail it for
these.

As a result regressions are now caught for OpenCL CPU and GPU devices.

Fixes #1873
