[SYCL][E2E] Add test to cover std::complex<float/double> mul/div (#21622)
libdevice provides __mulsc3, __divsc3, __muldc3, __divdc3 to support
complex number multiplication and division in 'no-fast-math' mode on
Linux platform only. These 4 builtins are not invoked by user code but
inserted by compiler when handling complex mul/div expression. This PR
adds e2e test for these builtins explicitly, the testing logic is ported
from compiler-rt test suite for normal CPU platform:
