Many places in the ESP_SYSTEM are using CONFIG_FREERTOS_UNICORE instead of CONFIG_ESP_SYSTEM_SINGLE_CORE_MODE (GitHub PR)

Closes IDFGH-11333

:not CONFIG_FREERTOS_UNICORE: - On multi-core SoCs, try initializing some of the peripheral drivers from a task pinned to the second core. Interrupts are typically allocated on the same core where the peripheral driver initialization function runs. Therefore by running the initialization function on the second core, more interrupt inputs can be used.
:not CONFIG_ESP_SYSTEM_SINGLE_CORE_MODE: - On multi-core SoCs, try initializing some of the peripheral drivers from a task pinned to the second core. Interrupts are typically allocated on the same core where the peripheral driver initialization function runs. Therefore by running the initialization function on the second core, more interrupt inputs can be used.
- Determine the interrupts which can tolerate higher latency, and allocate them using ``ESP_INTR_FLAG_SHARED`` flag (optionally ORed with ``ESP_INTR_FLAG_LOWMED``). Using this flag for two or more peripherals will let them use a single interrupt input, and therefore save interrupt inputs for other peripherals. See :ref:`intr-alloc-shared-interrupts` above.
:not SOC_CPU_HAS_FLEXIBLE_INTC: - Some peripheral driver may default to allocating interrupts with ``ESP_INTR_FLAG_LEVEL1`` flag, so priority 2 and 3 interrupts do not get used by default. If :cpp:func:`esp_intr_dump` shows that some priority 2 or 3 interrupts are available, try changing the interrupt allocation flags when initializing the driver to ``ESP_INTR_FLAG_LEVEL2`` or ``ESP_INTR_FLAG_LEVEL3``.
- Check if some of the peripheral drivers do not need to be used all the time, and initialize or deinitialize them on demand. This can reduce the number of simultaneously allocated interrupts.
