Bugfix: ota fails with secure boot on for image size greater than 3.2MB

Browse Source 
When an OTA image size is larger than 50 MMU pages (approx. 3.2 MB), secure_boot_generate fails while trying to map it into memory:
https://gitlab.espressif.cn:6688/idf/esp-idf/blob/master/components/bootloader_support/src/esp32/secure_boot.c#L72
Instead of trying to map the whole image, secure boot code should split the image into chunks and map them one by one, like it is done in esp_image_format.c:
https://gitlab.espressif.cn:6688/idf/esp-idf/blob/master/components/bootloader_support/src/esp_image_format.c#L372

Closes https://jira.espressif.com:8443/browse/IDF-709
