Update screwdriver to 2024 realities

[tlaurion]

Not coreboot devel here, but some discussions happened today on that subject with some anchors having been layed down at linuxboot/heads-wiki#120 (comment)

Question is: what could screwdriver add to support coreboot in 2024 on newer platforms, and if approaches cannot be generalized, what can be tought outside of the box to enable log capture upon failed memory taining or a machie not posting anymore, after the fact?

One idea is to update speaker console output (song given only when machine not posting) sending buffered logs to speaker.
Another is having screwdriver support all current debugging outputs that coreboot can enable.

Collaboration beteen coreboot devels and @lynxis needed.
