wuzhenghui f8ce91665e fix(bootloader_support): fix RTC retain mem offset for secure boot fast wakeup
Pointer arithmetic on rtc_retain_mem_t* subtracted ESP_SECURE_BOOT_DIGEST_LEN
in struct units instead of bytes. Cast through uintptr_t so retain mem stays
below the ROM verified-image digest region on deep-sleep wake.

Partial backport of !51265 (bootloader_common_loader.c only).

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.)
