fix(cpus): workaround for Cortex-A720 erratum 2729604

Cortex-A720 erratum 2729604 is a Cat B erratum that applies to
revisions r0p0 and r0p1, and is fixed in r0p2.

This workaround might impact performance of workloads heavily
relying on floating point division or square root operations.

fix(cpus): workaround for Neoverse-V2 erratum 3701771

Neoverse-V2 erratum 3701771 that applies to r0p0, r0p1, r0p2 is
still Open.

The workaround is for EL3 software that performs context save/restore
on a change of Security state to use a value of SCR_EL3.NS when
accessing ICH_VMCR_EL2 that reflects the Security state that owns the
data being saved or restored.

The mitigation is implemented in commit 7455cd172 and this patch should be applied on top of it.

fix(fvp): do not unregister the console on system suspend

On PSCI SYSTEM_SUSPEND, Arm platforms will call
arm_system_pwr_domain_save() which will call arm_console_runtime_end().
Usually (eg CSS), that's just a flush, but on FVP that also unregisters
the console. On HW_ASSISTED_COHERENCY=0 builds, this has the potential
to break and prevent any EL3 output after a SYSTEM_SUSPEND.

This happens because the calls to
console_unregister()/console_register() will overwrite the value of the
console_list variable in drivers/console/multi_console.c. They are
only called on a system level suspend. The bug happens when the core
wakes up. The console will be registered again as part of the
pwr_domain_suspend_finish() call. However, this call happens before the
data caches have been enabled in psci_do_pwrup_cache_maintenance(). As a
result, the write to console_list will not be reflected in the L2 cache
and other cores will not be able to read the new value.

The fix is to not unregister the console like other Arm platforms -
we don't need to reinitialise the console so there's nothing to do.

A nice side effect is that arm_console_runtime_end() no longer needs to
be weak.

chore(vscode): ignore noisy directories

Some directories undergo a high level of churn due to developer tooling
and contain little of use to the developer in day-to-day work. Including
them in the VS Code project can cause the editor to consume significant
system resources unnecessarily.

This commit updates the Visual Studio configuration to avoid showing,
watching or searching these directories, reducing resource usage and
improving editor responsiveness.

Neoverse-V2 erratum 3841324 is a Cat B erratum that applies to
r0p0 and r0p1. It is fixed in r0p2.

This erratum can be avoided by setting CPUACTLR_EL1[1]
prior to enabling MMU. This bit will disable a branch predictor
power savings feature. Disabling this power feature
results in negligible power movement and no performance impact.
