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]
