Startup optimization

 Bug: 5019676
 Save one thread by letting CrashRecoveryHandler re-use the BrowserSettings
 startup thread

 Lazy initialize the wake lock only if we need it (avoids IPC overhead at startup)

 Slight ordering shuffle in BrowserActivity to maximize the usefulness of the
 BrowserSettings startup thread
