bootloader_support: fix stringop-overflow warning with `PERF` compiler optimization
This commit fixes build issue because of function `bootloader_common_reset_rtc_retain_mem` getting inlined with compiler optimization level set to `PERF` (-O2). Build failure log: ----------------- In function 'bootloader_common_reset_rtc_retain_mem', inlined from 'bootloader_common_update_rtc_retain_mem' at /h/esp-idf/components/bootloader_support/src/bootloader_common_loader.c:183:13: /h/esp-idf/components/bootloader_support/src/bootloader_common_loader.c:159:5: error: 'memset' writing 16 bytes into a region of size 0 overflows the destination [-Werror=stringop-overflow=] 159 | memset(rtc_retain_mem, 0, sizeof(rtc_retain_mem_t)); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~pull/10970/head
