Replaces the per-function ``__attribute__((optimize("O2")))`` approach in
#15693 with a direct inline definition of micros() / millis_64() in hal.h
for ESP32, plus inline definitions for ESP8266 micros() and RP2040
millis()/millis_64().
The original goal of #15693 was to inline micros() into the main loop so
that ``call esphome::micros() → call esp_timer_get_time()`` collapses to
a single ``call esp_timer_get_time``. That wrapper-collapse benefits
every micros() call site, not just loop_task — so the real fix is to
mark the wrapper inline, not to bump the loop's optimization level.
Doing this at the HAL layer also makes runtime_stats measurements more
accurate: each timing read no longer hides a wrapper call/return between
the component end-time capture and the underlying clock read.
Refactor: move ``micros_to_millis<>()`` from helpers.h to a new
lightweight ``time_conversion.h`` so hal.h can include it without
pulling the rest of helpers.h into every TU that includes hal.h.
