refactor(esp_system): deduplicate ROM fast wake RTC digest reservation

Browse Source 
The digest length and the condition that reserves it at the end of RTC RAM were
duplicated in seven places. Hold the reservation in a hidden Kconfig value that
is zero when the feature does not apply, so every consumer subtracts it
unconditionally, and derive ESP_SECURE_BOOT_DIGEST_LEN from it.
