Targets

• corstone300: properly enable-disable fpu/mvei via cmdline args
• ARM: add proper handling of active features and mcpu string
• RISC-V: refoctor handling of extensions and arch string

• Support usage of gdbserver feature with ovpsim target

Setup

• Add --visualize to mlonmcu setup command to visualize task-dependencies via DOT
• Update download link to RISC-V GCC

CI/CD

• Add scripts/bench.py script as an abstract wrapper to invoke pre-defined benchmarks
• Define some basic benchmarks.
• New job: trigger benchmarks defined in scripts/[benchmarks.ini](https://github.com/tum-ei-eda/mlonmcu/blob/philippvk/scripts/benchmarks.ini)
