Update all FireSim workloads to Marshal configs

[abejgonzalez]

Instead of using the older method of generating a rootfs from the .json workload file, instead, standardize to using FireMarshal workload definitions for the workloads.

TODO/Things to note:

• Test all workloads to ensure they still work (They were tested briefly with QEMU/Spike but failed since some require networked connections).
• I removed the GAPBS scripts since the directory was not specified / the workload was broken (probably should fix)
• When installing the workload, a folder is generated in deploy/workloads that isn't tracked in the .gitignore (probably need to rework the .gitignore a bit
• Individually port each of the workloads in separate PRs for less PR reviewer burden. Separate out Chipyard bump
• What to do with checksum-test? Probably go back in history and see if this was working?
