feat: Upgrade view sdk (#2969)

<!-- Feel free to delete comments as you fill this in -->
- add acceptance clients for aggregation and projection policies (with
jiras to use proper SDK clients)
- adjust SDK to match snowflake
- change handling of `PolicyReference` to be more generic
- add new sturct `ExtendedIn` to handle SHOWs that can specify
applications and applications packages (will be useful in other
resources)
- add more validations
- add quotes for fields with column names
- update resource and datasource to be compatible with sdk
- update statuses of remaining objects
- NOTE: view behavior is not consistent with docs, that is:
    - adding columns is not working
- columns with options in CREATE are without () in docs - this is not
correct, they need to be wrapped in (), this will be reported on
doc-discuss
