[BUG] Compilation failure for SYCL with Intel oneAPI 2025.0 #596
Description
Current Behavior:
The PelePhysics CI is failing while compiling Sundials with SYCL support. The error is reproduced below - the std::sqrt function is not found. This is new behavior for Intel oneAPI 2025.0 (released 10/25/24) and does not occur for older versions.

Expected Behavior:
Sundials should compile successfully with Intel oneAPI 2025.0.
Steps To Reproduce:
Haven't reproduced locally, just by running the PelePhysics-CI workflow.
Environment:
- SUNDIALS version: 7.1.1
- OS: Ubuntu 24.04
- Intel oneAPI 2025.0
