soc: esp32: Added rodata injection to esp32 build

[melka]

When building for ESP32, the linker scripts were not loaded by zephyr_linker_sources.
This PR fixes that and allows custom linker scripts to be added to the build.

Shoutout to Sylvio on Zephyr discord for the solution.

@melka, sorry. Code is correct but you have to fix the commits. Please, squash them all in a single one. Also, start with soc: esp32: in the commit title. The middle one is correct: 893cb20

Aside the comments, LGTM

Hey @sylvioalves, I tried to do the requested changes but I am bad at git commits and PR requests, so let me know if I should redo it again. Sorry for the inconvenience, not used to working on big projects like this one.

1. Both description lines are too big. Break them. (max 75 chars in a single line).
2. As from guidelines, sign-off is required in every commit message. Use git commit -s to add it next time. In your case, I guess your Signed-off-by is missing < and > surrounding the email.
