[esp8266] Replace delay() with yield loop to allow GC of original millis
...
Arduino's ::delay() is implemented in core_esp8266_wiring.cpp alongside
millis(). Because __delay calls millis() within the same compilation
unit, --wrap=millis can't intercept that intra-object reference, which
prevents the linker from garbage-collecting the original millis body
(~80 bytes of IRAM).
Replace esphome::delay() with a simple yield loop that uses our fast
millis() accumulator. This has the same behavior as Arduino's delay:
feeds the watchdog and processes SDK tasks via yield(), keeping WiFi
alive. With __delay unreferenced, the linker can now GC both __delay
and the original millis function.

[esp8266] Replace millis() with fast accumulator, wrap Arduino callers
...
Arduino ESP8266's millis() uses 4x 64-bit multiplies with magic
constants to convert system_get_time() to ms while tracking overflow.
On the LX106 (no hardware multiply-high instruction), each 64-bit
multiply goes through the __umulsidi3 software helper — costing
~3.3 us per call.
Replace with a simple accumulator that tracks a running millis counter
from system_get_time() deltas using pure 32-bit integer ops (subtract,
add, compare, subtract). No 64-bit math, no __umulsidi3.
Use -Wl,--wrap=millis to intercept all ::millis() calls site-wide so
Arduino libraries and ISR handlers (Wiegand, ZyAura) also get the fast
version. Brief interrupt disable (~125 ns) protects the static state.
Overflow safety: unsigned 32-bit delta arithmetic handles the 71-minute
system_get_time() wrap correctly for one wrap. ESPHome calls millis()
thousands of times per second, so missing a full wrap is not a realistic
concern. At boot, both the accumulator and system_get_time() start at 0,
so no special initialization is needed.
Benchmarked on real ESP8266 hardware:
Before: 3348 ns/call (Arduino 4x 64-bit multiply)
After: ~800-900 ns/call (accumulator, estimated)
