Replace the flag used in src to use newly added flag in ag/27264595.

Add a new feature flag - "network_provider_battery_charging_status" in
android.net.wifi package.
It is the same flag which was added in ag/25092320 in the wifi module.

framework-minus-apex depends on a flag defined in wifi_aconfig_flags
but framework-minus-apex does not depend on the corresponding aconfig
java lib wifi_aconfig_flags_lib. Therefore Soong doesn't know about
the dependency -> Soong won't tell Metalava about the flag ->
Metalava will default to reverting the API to the previous SDK
snapshot -> API will not be present in the SDK and docs artifacts.

Solution:
1) define a new flag in frameworks/base
2) Work with relteam to ramp it to next ASAP
3) Move NetworkProviderInfo to use this new flag

mechanism in WifiKeystore.

See aosp/2859045 as an example of using
ConnectivityBlobStore.

The expected behavior per-API is:

 - put: Always write to ConnectivityBlobStore.
 - get: Attempt to get from ConnectivityBlobStore.
        If alias is not found there, try checking
        in LegacyKeystore.
 - remove: Remove alias from both ConnectivityBlobStore
           and LegacyKeystore.
 - list: List aliases from both ConnectivityBlobStore
         and LegacyKeystore. Deduplicate before returning.

Before calling a flagged API, client code must check the value of the flag
which gates it. Those flags must be exported in order to be accessible from
containers other than the container where the flag and the API are hosted.

teardownInterfaces in WifiNl80211Manager.

Prevents a specific race condition when the wificond
service dies at the same time as the Vendor HAL (whose
death handler calls into teardownInterfaces).

No other race conditions have been observed in this file,
so we can limit the locks to these 2 methods.

mService is used by registerCallback as an indication of if the service is bound to. This was only being set to null when the service was unbound from the service side, not when unbound from the manager side.
