WifiLastResortWatchdog: Clear failure counts on HAL init
These counters should be reset whenever we restart wpa_supplicant and
initialize the HAL.
This is to clear these counters on wifi stack restarts (internal or user
initiated).
Bug: 38422186
Test: Unit tests

SelfRecovery: Module for initiating internal stack restarts
Adding a new module for initiating stack restarts when we detect some
kind of failure internally. This module essentially moves the
|restartWifiStack| functionality out of WifiLastResortWatchdog so that it
can be reused by WifiStateMachine for HAL/wificond crashes.
The 3 reasons for triggering self recovery currently are:
1. Last resort watchdog bite.
2. HAL crash.
3. Wificond crash.
TBD: We could potentially perform the same recovery on a supplicant crash.
Bug: 36586897
Test: Manual tests by crashing the HAL & wificond.
Test: Unit tests.

WiFiMetrics: Add LastResortWatchdog success metric
Added a metric that tracks how often WifiLastResortWatchdog triggers
successfully fix wifi, allowing wifi to connect to a network after
triggering. It does not count a success, if the connection occurs
after a new network becomes available.

WifiInjector: add WifiServiceImpl objects
Move objects created in WifiServiceImpl into WifiInjector to facilitate
unittests. The first call should be to create an instance of
WifiInjector. This call takes the Context as a parameter and is used to
initialize the instance. This instance is also stored in the class and
subsequent calls should use the WifiInjector.getInstance() call.
Exceptions are thrown if the constructor is called multiple times or
will a null Context parameter. An exception is also thrown if
getInstance is called before the WifiInjector constructor has been
called.
This change also allows the setWifiController method of
WifiLastResortWatchdog to be removed.
This change also removes the local variable for the
WifiLastResortWatchdog instance in WifiStateMachine. Instead of holding
the LastResortWatchdog, calls from WifiStateMachine will get the
instance from WifiInjector when they are needed. This is due to the
dependence triangle between WifiStateMachine, WifiController and
WifiLastResortWatchdog.

WifiLastResortWatchdog: dynamic verbose logging
Switch WifiLastResortWatchdog over to using the dynamic support for wifi
verbose logging.
This CL also cleans up some logging to remove misleading ages for
network summary information.

WifiLastResortWatchdog: reset wifi on trigger
Added wifi reset on WifiLastResortTrigger. The reset is implemented by
sending the CMD_RESTART_WIFI message to WifiController.

WifiLastResortWatchdog: update config if not null
When new scan results are processed, networks already stored as the
available networks may have updated configs passed in, but they may also
have null configs. The null configs should not be used to update the
stored config. Added a check to determine if the passed in config is
not null before the update.
In addition, debugging output also reported the value of
HasEverConnected as false for networks with a null config. This was
updated to report null_config instead.
Added tests covering config updates.
Added tests for debugging output.

WifiLastResortWatchdog metrics
Added logging of various metrics to the WifiLastResortWatchdog. These
metrics count the number of times the Watchdog triggers, and stats
counting the number of networks present at failure time for different
failure types.

WifiLastResortWatchdog trigger logic
Implemented trigger condition logic that is checked after a failure is
counted. The condition takes into account: failure counts, wifi
connected state, past connections to saved networks and whether the
watchdog has fired since the wifi environment changed.
Please note: This change only implements the logic for deciding when to
trigger, not the trigger itself.

WifiLastResortWatchdog failure counting
Implemented watchdog methods and calls to them from WifiStateMachine to
count association rejection, authentication failure & dhcp failures.
This will allow the watchdog to determine when all available networks
are failing, and Wifi Framework has no other options, however this Cl
does not implement that logic.

Created LastResortWatchdog class
Created the WifiLastResortWatchdog class, that will handle restarting
the wifi stack as a last resort when wifi is failing.
Implemented the logic that tracks failure counts for all available
networks, and the maintaining of that list of available networks.
