* @brief Disable and free an interrupt.

* Use an interrupt handle to disable the interrupt and release the resources
* associated with it.
* Use an interrupt handle to disable the interrupt and release the resources associated with it.
* If the current core is not the core that registered this interrupt, this routine will be assigned to
* the core that allocated this interrupt, blocking and waiting until the resource is successfully released.
*
* @note
* When the handler shares its source with other handlers, the interrupt status
* bits it's responsible for should be managed properly before freeing it. see
* ``esp_intr_disable`` for more details.
* ``esp_intr_disable`` for more details. Please do not call this function in ``esp_ipc_call_blocking``.
*
* @param handle The handle, as obtained by esp_intr_alloc or esp_intr_alloc_intrstatus
*
* @return ESP_ERR_INVALID_ARG if handle is invalid, or esp_intr_free runs on another core than
* where the interrupt is allocated on.
* @return ESP_ERR_INVALID_ARG the handle is NULL
* ESP_FAIL failed to release this handle
* ESP_OK otherwise
