[dannywillems]

Import all MIPS programs from Optimism, and tweak it to make it compatible with our ELF loader. Requested by @martyall to have more small test programs for the o1vm MIPS edition.

This is super useful! My only request is that the linked files shouldn't be committed, i.e. the entire resources/programs/{mips,riscv}/bin directory should be ignored (not just the object files). It seems like this was also your intention since make clean blows this directory away.

The only issue I see by not committing them is that the CI (and users) will have to build them, and therefore would need to add the mips toolchain on their machine.

That's a fair point that it's annoying to require it for devs, it just seems weird that running make clean creates a diff by deleting them.

BTW I can confirm that these are working with #2911 .

@dannywillems I would suggest that we use a github workflow with a workflow_dispatch trigger to be able to run this job in ci and tar/upload the artifacts. This way we can still ignore the bin directory and make clean is really clean (as opposed to "dirty"). Developers who don't want to build the binary files from source (e.g. mac users) can just download and unzip.

I implemented this strategy in #2911. You can see what this workflow looks like here, and here is an example upload

I did remove the commit 49235d3 to clean the history and avoid unnecessary commits. #2911 would therefore need a rebase.
