feat!: update gcc-10 to gcc-12

[Ron (rjaegers)]

• Update host gcc from version 10 to version 12
• Update arm-none-eabi from version 10 to version 12
• Add gdb-multiarch in favor of arm-none-eabi-gdb since it has some dependencies (ncurses5 and python3.8 that we don't want to satisfy)

Looks good. I have a question though: Will the file structure stay the same when we add more compilers/debug tools?

We are not intending on adding more compilers. Tools can be added both in the Dockerfile (for non-apt sources) or in the JSON files for apt sources.

Previously we had the plan to simultaneously support multiple compiler version permutations. But we have abandoned that idea for now.
