J. Nick Koston e5a0246c80 [core] Document clock divergence between millis() and millis_64_from_() 
On ESP32, millis() uses xTaskGetTickCount (tick clock) but
millis_64_from_() discards the 32-bit value and calls millis_64()
(esp_timer clock). Safe because scheduling only compares millis_64
against millis_64. On ESP8266, both use the same accumulator clock.

J. Nick Koston 0249c30cbf [esp32] Document why millis_64() uses a different clock than millis() 
millis() uses xTaskGetTickCount (tick clock) while millis_64() uses
esp_timer_get_time (hardware timer). Safe because they are never
cross-compared: Scheduler::millis_64_from_() on ESP32 discards the
32-bit millis parameter and calls millis_64() directly, keeping all
64-bit scheduling on the esp_timer clock.

J. Nick Koston b5a2d58b80 [esp32] Keep millis() out-of-line with IRAM_ATTR, add ISR context check 
Revert the inline hal.h approach — millis() must remain IRAM_ATTR
because Wiegand and ZyAura call it from IRAM_ATTR ISR handlers on
all platforms including ESP32.

Use xPortInIsrContext() to dispatch to xTaskGetTickCountFromISR()
from ISR or xTaskGetTickCount() from task context, satisfying the
FreeRTOS API contract. ISR check is [[unlikely]] so the hot path
stays fast.

Benchmarked: 686 ns -> 361 ns (1.9x faster). Correctness verified.

J. Nick Koston c155f41110 [esp32] Inline millis() in hal.h, drop IRAM_ATTR 
Move millis() to an inline function in hal.h that just returns
xTaskGetTickCount() -- eliminates the function call entirely at every
call site. No IRAM consumed, no flash function call.

Drop IRAM_ATTR from the fallback path. The original IRAM placement was
inherited from ESP8266 where Arduino millis() is called from ISR
handlers (Wiegand, ZyAura). ESPHome does not call millis() from ISR
on ESP32.

J. Nick Koston 6ac705cd66 [esp32] Use xTaskGetTickCount() for millis() when tick rate is 1kHz 
ESPHome sets CONFIG_FREERTOS_HZ=1000, so one FreeRTOS tick equals one
millisecond and xTaskGetTickCount() returns ms directly. This replaces
esp_timer_get_time() + micros_to_millis() (a hardware timer read plus
a 64-bit multiply-shift conversion) with a single volatile memory read.

Benchmarked on real ESP32 hardware:
  Before: 686 ns/call (esp_timer_get_time + micros_to_millis)
  After:  ~20 ns/call (volatile read of xTickCount)

millis() is called 1+N times per main loop iteration (once at the top
and once per component via WarnIfComponentBlockingGuard::finish()), so
on a 5-component device this saves ~3.4 μs per loop iteration.

millis_64() is left on esp_timer_get_time() for full 64-bit μs
precision — it is only called once per loop by the Scheduler.
micros() is also unchanged (runtime_stats needs μs precision).

Falls back to the original implementation if CONFIG_FREERTOS_HZ != 1000
(non-standard user override).
