soc: esp32xx: always use section prologue with alignment

Browse source 
ESP32 requires proper alignment between sections. There are some
scenarios, as reported in #74533, that the section can
get shifted, causing runtime failure.
Making sure SECTION_PROLOGUE is used with ALIGN_WITH_INPUT
will guarantee its consistency.

Fixes #74533
