init: Factor out AppInitLockDataDirectory

Browse Source 
Alternative to #10818, alternative solution to #10815.

After this change: All the AppInit steps before and inclusive
AppInitLockDataDirectory must not have Shutdown() called in case of
failure. Only when AppInitMain fails, Shutdown should be called.

Changes the GUI and bitcoind code to consistently do this.
