GitLab

The directory structure before:

<ProfileDir>
    WebApps
        Sync Data
            LevelDB
        Temp
            <temp_name>
        <app_id>
    Web Applications
        _crx_<app_id>

After:

<ProfileDir>
    Web Applications
        _crx_<app_id>
        Sync Data
            LevelDB
        Temp
            <temp_name>
        Manifest Resources
            <app_id>

This is breaking change, all local BMO profile icons will be
clean. We should land it now to avoid file migrations in the
future.

Note: "Sync Data/LevelDB" directory is created only if
kDesktopPWAsSharedStoreService feature is off.
We use shared <ProfileDir>/Sync Data/LevelDB/ otherwise.

This code is disabled behind kDesktopPWAsWithoutExtensions feature.
It introduces no behavior changes.
