Work-group sizes currently rely on device maximum rather than the max from a kernel query. This changes aims to allow querying the kernels by using kernel bundles in the reduction implementations. In order to do that, all kernel functions have to be defined as function objects and given unique names (for the `kernel_id`s), so they can be identified for a kernel_bundle to be obtained. Additionally, the kernel_bundle can be used with the command group execution to ensure we exeucte the same kernel we queried. This has been added as an optional and can be user-configured via `SYCL_REDUCTION_ENABLE_USE_KERNEL_BUNDLES=1|0`. It is set to 0 by default, which means `use_kernel_bundle` is not called. The goal of this is to be do `kernel.get_info<kernel_device_specific>` (i.e. `work_group_size`) queries, primarily to make sure that safe work-group sizes are chosen, but also for other capability queries which can be use for the implementations of the different kernel startegies.

Problem statement
Work-group sizes currently rely on device maximum rather than the max from a kernel query.
Changes overview
This changes aims to allow querying the kernels by using kernel bundles in the reduction implementations.
In order to do that, all kernel functions have to be defined as function objects and given unique names (for the
kernel_ids), so they can be identified for akernel_bundleto be obtained.Additionally, the
kernel_bundlecan be used with the command group execution to ensure we exeucte the same kernel we queried. This has been added as an optional and can be user-configured viaSYCL_REDUCTION_ENABLE_USE_KERNEL_BUNDLES=1|0. It is set to 0 by default, which meansuse_kernel_bundleis not called.End Goal
The goal of this is to be able to do
kernel.get_info<kernel_device_specific::<query_value_here>>(i.e.work_group_size) queries, primarily to make sure that safe work-group sizes (not device maximums but kernel maximums) are chosen. This will also benefit us with querying other kernel-device-specific capabilities which can be used for implementing (or optimizing) the different kernel strategies to be as efficient as possible.
