80eb8be3cf configs: Update Arm simple configs to enable --interactive option 
Removed the calls to `sys.exit()` from the Arm simple configs. These
calls terminate gem5's embedded Python interpreter and gem5 at the end
of the config script, preventing gem5 from dropping into the
interactive IPython shell when the `--interactive` option has been
specified.

a83f699f1d configs: Add Tarmac tracing option to the simple Arm configs 
gem5 supports Tarmac trace generation for Arm simulations, but there
are no examples of how to use this feature.

This patch adds a `--tarmac-gen` option to three of the simple Arm
configs. Tarmac generation is useful for out-of-the-box users, and
this patch also provides an example of how to use the Tarmac
generation feature.

d1d90c529c configs: Stop using a PTW cache before L2 in Arm configs 
This implementation of a walk cache does not allow to skip walks as it
is a simple cache placed in front of the table walker.
It was meant to provide a faster retrieval of page table descriptors
than fetching them from L2 or memory.

This is not needed anymore for Arm as from [1] we implement
partial translation caching in Arm TLBs.

a680b98eaf configs: Assign the host gid to the Process.gid in SE configs 
Some syscalls (like chown) can make use of the current process group id
(gid) to setup file ownership. If we just provide the default fake gid
([1]) we will encounter some problems when executing the syscall on the
host.

Example (guest) program:

gid_t prc_gid = getgid();
int res = chown(..., prc_gid);

By assigning the host gid to the guest we are sure we can successfully
execute syscalls from the gem5 process

3293926413 sim: Create a Workload object for SE mode. 
The workload object is still optional for the sake of compatibility,
even though it probably shouldn't be in the long term. If a simulation
is just a collection of components with nothing in particular running on
it, for instance driven by a traffic generator, should it even have a
System object in the first place?
