Add kernel launch support

[szymon-zadworny]

This PR adds:

• support for launching 1, 2 and 3 dimensional kernels
• NdRange reimplementation
• a set of traits for defining valid SYCL kernel arguments
• a kernel launch example

Note: The argument passing syntax is not final. This PR mainly provides scaffolding for future macro-related work.

Pull request overview

This PR introduces a first pass at SYCL kernel launch support in the oneapi-rs Rust wrapper by adding ND-range abstractions, kernel bundle/kernel types, and the FFI plumbing needed to build kernels from source and launch them with raw argument passing.

Changes:

• Add Context, kernel bundle, and kernel abstractions, plus an example that compiles source and launches a kernel.
• Introduce NdRange/Range and queue-side launch APIs for 1D/2D/3D kernel dispatch.
• Extend oneapi-rs-sys C++/cxx bridge types and queue/context/kernel-bundle shims to support the new functionality.
