Neither yield() nor delay() can be called from ISR context or during flash operations. yield() calls vPortYield/::yield which are not ISR-safe, and delay() calls vTaskDelay/::delay which block the calling task. IRAM_ATTR was applied as a blanket attribute when the HAL abstraction was created in 2021 (#2303) but was never actually needed for these two functions. Retains HOT attribute for compiler optimization hints.
