OpenAPI for Views

[mike12345567]

Description

Expanding the public API to have a set of endpoints for CRUD on views as well as searching views.

The following endpoints have been added:

• POST /api/public/v1/views - create a view
• PUT /api/public/v1/views/:viewId - update a view
• DELETE /api/public/v1/views/:viewId - delete a view
• GET /api/public/v1/views/:viewId - retrieve a single view by ID
• POST /api/public/v1/views/search - search for a view across all tables by name
• POST /api/public/v1/views/:viewId/rows/search - search for rows within a view

This also fixes https://github.com/Budibase/budibase/issues/15041 by setting the CORS headers for the public API correctly to allow using the public API directly from the browser.

Also important to note most of the new additions are the updates to the openapi.json and openapi.yaml that need committed to the repo so that readme has access to them.
