soc: espressif: provide VMA to rodata and text by default

Flash segments require VMA to proper work. Executing from LMA
is not possible. Current implementation did not take into account
runtime iterable rom sections that any application could implement.
In the above cenario and as reported in the issue below, ESP32 won't run
when those ROM sections are created in application level.

This change make sure all flash segments are properly mapped
accordingly.

Fixes #61834
