[core] Match wake storage conditionals across platform TUs

Browse Source 
ESPHome's defines.h unconditionally #defines every feature flag for
static analysis, so clang-tidy sees ESPHOME_THREAD_MULTI_ATOMICS even
when building wake_esp8266.cpp / wake_rp2040.cpp / wake_generic.cpp.
In that mode wake.h picks the std::atomic<uint8_t> extern, and the
plain-volatile definitions in those TUs trip a redefinition error.

Guard each TU's g_wake_requested with the same
ESPHOME_THREAD_MULTI_ATOMICS check wake.h uses. Real builds still pick
volatile on every SINGLE platform.
