Cw 155 monero synchronization (#1014)

* Run Monero Synchronization task in background on Android

* Add monero sync task in the load function to be registered/cancelled when user changes wallets

* Revert unused file changes

* Register Sync task on all monero wallets if any

* Add Sync Modes and change task frequency based on user's choice

* Register background task after current wallet is set

* Add Sync All toggle and change task wallets to sync accordingly

* Enable background notifications in release mode temporarily

* Disable constraints and increase the frequency of tasks

* Decrease frequency of background tasks

* Delay the background task thread till the syncing thread finish (Dummy Trial-1)

* Start Sync process and wait for it to finish

* Wait for synchronization to finish before ending the background thread
Add 10 minutes timeout duration for sync process

* Connect to node before syncing wallet

* replace testing configuration with the configurations agreed on

* Fix Conflicts with main

* Update and Migrate Background tasks to null safety

* Update workmanager version in pubspec_base also

* Move Sync options to Connection and sync page
Show Sync options only for Monero and Haven
Minor Enhancements

* Remove debugging notifications
Revert aggressive mode frequency to 6 hours [skip ci]

* Add iOS configs

* Revert debugging changes
Fix conflicts with main

* Add/Extract Sync configurations to/from backup file [skip ci]
