feat: promote all qemu/cortex components to cortex_m

[gabrielfrasantos]

Summary

• SystemTick (Move hal/qemu/cortex/SystemTick to hal/cortex_m/SystemTick #101), SystemTickTimerService (Move hal/qemu/cortex/SystemTickTimerService to hal/cortex_m/SystemTickTimerService #102), Reset (Generalize hal/qemu/cortex/Reset to hal/cortex_m/Reset #100), EventDispatcherCortex, and Semihosting are all moved from hal/qemu/cortex/ to hal/cortex_m/ so any downstream Cortex-M HAL can use them without reimplementing locally or depending on the QEMU gate (EMIL_BUILD_QEMU).
• hal::cortex::Reset now implements hal::Reset (ResetModule(const char* resetReason)) — the resetReason parameter is accepted and ignored at this layer; callers are responsible for tracing before reset.
• EventDispatcherCortexWorker switches its base from EventDispatcherWithWeakPtrWorker to EventDispatcherWorkerImpl and adopts the DSB+WFE/SEV pattern for proper ARM sleep/wakeup (memory barrier before sleep, send-event to unblock a waiting core/interrupt), replacing the bare wfi.
• hal.qemu.cortex becomes a CMake INTERFACE library (no compilation units remain) and continues to expose hal.cortex_m, infra.event, infra.timer, and hal.interfaces to its five existing consumers without requiring changes at their call sites.
• Issue hal::TimeKeeperGeneric vs. a hal/cortex_m/TimeKeeper — which is the intended pattern for injected timer-service consumers? #103 (TimeKeeperGeneric vs injected TimeKeeper) was answered and closed — TimeKeeperGeneric is the correct pattern once SystemTickTimerService is registered.

Test plan

• cmake --preset host && cmake --build --preset host-Debug builds cleanly
• ctest --preset host passes (host-side tests unaffected by embedded-only changes)
• cmake --preset embedded && cmake --build --preset embedded builds cleanly for Cortex-M targets
• QEMU integration test (hal.qemu.test) passes — TestSystemTickTimerService exercises the promoted SystemTickTimerService from its new location
