[codex] Add CPU topology spoofing

[Chel-Tbl]

Summary

• Add per-profile [Scheduler.CPUSpoof] settings for enabled state, logical processors, and physical cores.
• Spoof common CPU topology entry points including GetLogicalProcessorInformation(Ex), GetSystemInfo, active/max processor counts, process affinity, threadpool limits, and MSVCP hardware concurrency.
• Install the topology spoof path early and patch loaded-module imports / GetProcAddress / LoadLibrary* so games that query CPU topology during startup can see the configured topology.
• Add control-panel UI for Spoof CPU Topology plus optional Windows AppCompat ProcessorCountLie SDB install/uninstall helpers.
• Add worker-thread diagnostics and CPU monitor/widget bounds checks for spoofed topology scenarios.

Paired SKIF PR

Launcher support is in SpecialKO/SKIF#56. That paired change forwards CPU-topology-enabled launches through SKIF's suspended early-injection path and makes config reset remove generated CPU topology SDB artifacts.

Validation

• $env:CL='/wd4828'; msbuild SpecialK.sln /m /p:Configuration=Release /p:Platform=x64 /p:VCToolsVersion=14.44.35207 /v:minimal
• git diff --cached --check

/wd4828 was needed only to get past an existing NVAPI header codepage warning that VS18 otherwise treats as fatal before compiling the changed files.
