SYCL toolchain build issues with XPTI

[abagusetty]

Describe the bug

Faced with build errors from XPTI when building HIP backend for AMD using gcc-13.3.0 and rocm-6.3.0

Configured with:

CC=`which gcc` CXX=`which g++` python3 ./buildbot/configure.py -t Release --native_cpu --hip --hip-platform AMD --llvm-external-projects openmp --cmake-opt="-DUR_HIP_ROCM_DIR=/soft/compilers/rocm/rocm-6.3.0"

Some of the build errors are shown below:

/vast/users/abagusetty/compilers/today/llvm/xpti/../xpti/include/xpti/xpti_trace_framework.h:149:11: error: ‘xpti’ does not name a type
