Omar Chebib 1e8b9f8b9c fix(bootloader): add legacy retained memory CRC calculation 
* Closes https://github.com/espressif/esp-idf/issues/12849

In former versions of ESP-IDF, the user custom memory data in the retained memory
was taken into account during the CRC calculation. This was changed in a later
commit, the custom memory was ignored, therefore this can seen as a breaking change.
This commit gives the possibility to choose between the former (legacy) or
new way of calculating the CRC.

Bootloader Support Component
============================

Overview
--------

"Bootloader support" contains APIs which are used by the bootloader but are also needed for the main app.

Code in this component needs to be aware of being executed in a bootloader environment (no RTOS available, BOOTLOADER_BUILD macro set) or in an esp-idf app environment (RTOS running, need locking support.)
