Added parameter to disable web UI integration with local client

Added system config parameter `web_ui_integration_local_client.enabled`
to allow disabling integration with local client from web UI (i.e. when
local Nextcloud clients are not used).

Use
```
occ config:system:set web_ui_integration_local_client.enabled --value='true' --type=boolean
```
to enable (default if not set) and
```
occ config:system:set web_ui_integration_local_client.enabled --value='false' --type=boolean
```
to disable  integration.

Use added parameter to show/hide `Edit locally` option in Nextcloud Files.
