feat(sycl): Define CEED_RUNNING_JIT_PASS in JIT

[jrwrigh]

Update to include CEED_RUNNING_JIT_PASS to the SYCL backend's definitions. This was added in #1696, but not to the SYCL backend.

Confirmed this works on Aurora.

@kris-rowe @uumesh Any foreseen issues with this?

[kris-rowe]

Not that I can think of. Does the kernel generation in the SYCL backend need to be updated to use include flags?

[uumesh]

Is this addition just for consistency? I don't think it will have any effect unless the JIT source is also modified.

For consistency, and also to allow including character arrays in the header files (see MR here). The latter is more for coding convenience than anything else.

Edit: We do have some HONEE jit sources that use CEED_RUNNING_JIT_PASS to ignore <math.h> and <stdbool.h> include directives, but evidently it's not necessary for the SYCL backend. See

libCEED/examples/fluids/qfunctions/advection.h

Lines 11 to 14 in 6001dc9

	#ifndef CEED_RUNNING_JIT_PASS
	#include <math.h>
	#include <stdbool.h>
	#endif

It'd probably be nice in the future, but it's not blocking anything in HONEE.

[uumesh]

That should be fine. I also see that the flag adds a guard to exclude std/math libraries from the QFunctions. I am not sure if that will affect the compilation of OpenCL kernels. For example in the advection functions here
If you can check that this test passes, the rest should be fine as well.

[jrwrigh]

It's been passing tests in HONEE, I'll double check with the libCEED tests real quick though. (HONEE should be a super set of the libCEED fluids tests).

Edit: All the fluids tests pass with the exception of a few segfaults, but those were present before as well.

This may be useful to add as well:
