Streamwrapper: Move logic out into the open

[rebeccahum]

Description

Similar to #4589, we should move this logic out into the open since it is already enabled for everyone. There is still the option to disable it with the constant VIP_FILESYSTEM_USE_STREAM_WRAPPER though.

This flips the logic and may result in breakage in Local Dev Env which didn't have the stream wrapper constant. This is being addressed here: Automattic/vip-container-images#517

But even when that's merged we don't update wp-config for existing environments.
