[SYCL][NFC] Refactor kernel property parsing

[uditagarwal97]

This PR refactors kernel property parsing in the SYCL implementation by consolidating property parsing logic from the handler into a centralized helper structure. The refactoring moves property validation and processing from handler.hpp into kernel_launch_helper.hpp, so that the same logic can be re-used on the no-handler path as well.

Pull Request Overview

This pull request refactors kernel property parsing in the SYCL implementation by consolidating property parsing logic from the handler into a centralized helper structure. The refactoring moves property validation and processing from handler.hpp into kernel_launch_helper.hpp, introducing a new PropsHolder structure for marshalling kernel properties and simplifying the handler interface.

• Introduces a new kernel_launch_properties_v1 namespace with PropsHolder and MarshalledProperty templates for centralizing property parsing
• Moves property validation logic from handler::processProperties to detail::processKernelProperties
• Adds handler::setKernelLaunchProperties method that delegates property processing to kernel_data.hpp

Out of curiosity, why do we need this guard?

[uditagarwal97]

This guard was stale - earlier we used to call into libsycl from parseProperties function. But, now that I've split parsing and setting/validation of properties it's no longer required. I've moved this guard to setKernelLauchProperties method instead.

Are you sure we still need this? Can we pass Kprop as-is down to the UR calls?
