Enable/disable preview for all the datasets when publishing Kedro-Viz from CLI

[jitu5]

Description

Resolves 1870

Development notes

• --include-preview flag added for Viz CLI:
• By default, kedro viz deploy and kedro viz build will have preview disabled for all the datasets
• Introduced a ClassVar is_all_previews_enabled for DataNodeMetadata class which controls the enable/disable functionality for all the datasets

QA notes

• Run kedro viz build --include-preview to enable preview for all datasets
• Run kedro viz deploy --include-preview to enable preview for all datasets in the deployed version

NOTE: As discussed with @rashidakanchwala and @stephkaiser , kedro viz run will not have a preview flag and preview will be set to True by default. If the users want to change this behavior, they need to do this from UI. Designs will be updated soon (cc: @stephkaiser )

There's also this ticket here #1705 , we can add this to next sprint.

One thought is perhaps to name the new boolean after the new --include-preview flag, so it's clear those two are connected?

@rashidakanchwala Sure I will create a separate PR for change of is_preview_disabled to is_preview_enabled
