[SYCL][NFC] Extract range rounding logic

[slawekptak]

Extract the range rounding logic to a separate header, so it can be used in both the handler and the queue (once the handler-less kernel submission logic uses range rounding).

[Copilot]

Pull request overview

This PR extracts range rounding logic from the handler class into a new separate header file (range_rounding.hpp) to enable code reuse. The refactoring prepares for handler-less kernel submission by making the range rounding utilities available to both handler and queue implementations.

Key Changes

• Creates new sycl/include/sycl/range_rounding.hpp header containing extracted range rounding classes and functions
• Moves range rounding logic from handler member functions to standalone functions in the detail namespace
• Updates ABI symbol exports to reflect the namespace change from handler:: to detail::
