kleines Filmröllchen 47b6030347 Meta: Replace run.sh by run.py 
A Python script is much easier to maintain than the organically grown
variable mess that was run.sh.

For now, the script inherits most environment variable modifiability
from the shell script, but this is not a requirement.

While porting this script, a couple of improvements have been made:
- Spaces (especially in paths) cannot break most arguments anymore.
  Exceptions are environment variables specifying multiple arguments on
  purpose, these should be replaced in the future anyways.
- Force control over virtualization is now possible with
  SERENITY_VIRTUALIZATION_SUPPORT. If set to 0, this variable was
  sometimes ignored before.
- Handling Windows native QEMU is much more robust. Multiple incorrect
  checks for WSL, but not Windows native QEMU, were used before. This
  would also allow disabling native Windows QEMU much more easily in the
  future, which is necessary for GDB.
- Various machine types had wrong or outdated arguments, such as qn.
