When BinderIncrementalService start, it call ps->giveThreadPoolName() change the thread name to Binder:%d_%X.
However BinderIncrementalService run in system_serve main thread, it need not change the thread name.

Test: Keystore 2.0 is used by certain system apps (Settings, Keychain)
      when enabled.

* changes:
  Add limited use keys related API into Keystore 2.0 SPI.
  Limited use key: feature flags.

* changes:
  Allow setting underlying networks when legacy lockdown enabled.
  Allow passing the underlying network to startLegacyVpn.

Currently, if a legacy lockdown VPN is up, no VPN can set
underlying networks. This does not make much sense.

When legacy lockdown VPN is enabled, no other VPN is allowed to
call prepare() or establish(), so no other VPN can connect, and
if no VPN can connect, then no VPN can set underlying networks.
Therefore, disabling the ability to set underlying networks only
affects the legacy lockdown VPN itself.

This change is necessary because in a future CL, the legacy
lockdown VPN will start to inform ConnectivityService of its
underlying network.

This will be used by a future change that makes the legacy
lockdown VPN pass the underlying network.
