feat: support information_schema.views

[neverchanje]

I hereby agree to the terms of the RisingWave Labs, Inc. Contributor License Agreement.

What's changed and what's your intention?

Support select * from information_schema.views;

The information_schema.views view contains information about all views
defined in the database.

The information_schema.views view contains the following columns.

Column	Type
table_catalog	varchar	Name of the current database
table_schema	varchar	Name of the schema that contains the view
table_name	varchar	Name of the view
view_definition	varchar	SQL statement that defines the view

Limitation: Any users who can access information_schema.views can access all views. There is a security risk here.

https://www.postgresql.org/docs/current/infoschema-views.html Only those views are shown that the current user has access to (by way of being the owner or having some privilege).

The same to information_schema.tables cc @yezizp2012
