Disable topology currently defaults to `false` (topology enabled...). Change this so that topology is enabled by default on hardware that may benefit from it (multiple NUMA nodes or LLCs) and disabled on hardware that does not benefit from it. This is a slightly noisy change as we have to move ownership of the newly mutable layer specs into the `Scheduler` object (previously they were a borrow). We don't have a `Topology` object to make the default decision from until `Scheduler::init`, and I think this is because of the possibility of hot plugs. We therefore have to clone the `Vec<LayerSpec>` each time as it is potentially mutable. Test plan: - CI. Updated to be explicit about topology in both cases. Single NUMA multi-LLC machine: ``` $ scx_layered --run-example ... 13:34:01 [INFO] Topology awareness not specified, selecting enabled based on hardware ... $ scx_layered --run-example --disable-topology=true ... 13:33:41 [INFO] Disabling topology awareness ... $ scx_layered --run-example -t ... 13:33:15 [INFO] Disabling topology awareness ... $ scx_layered --run-example --disable-topology=false # none of the above messages present ``` Single NUMA single LLC machine: ``` $ scx_layered --run-example 15:33:10 [INFO] Topology awareness not specified, selecting disabled based on hardware ``` |

RUST SCHEDULERS
Introduction
This directory contains schedulers with user space rust components.
The README in each scheduler directory provides some background and describes the types of workloads or scenarios they're designed to accommodate. For more details on any of these schedulers, please see the header comment in their main.rs or *.bpf.c files.
