[GraphQL/Cursor] Refactor Events Pagination (MystenLabs#15528)

## Descriptions

This PR applies the various preceding abstractions (cursor and
pagination frameworks) to `Query.eventConnection`, and renames it to
`Query.events`.

Events also support more expressive filters than previous types that we
applied these frameworks to, in particular, they support filtering by
modules and types, so we introduce `TypeFilter` and `ModuleFilter`
(string) scalars as a new abstraction responsible for:

- Parsing cascading filters of this kind.
- Applying them as filters onto existing queries.

The parsing implementation has also been made to uniformly rely on
Move's parser for types and identifiers (previously it used Move's
parser for types, but string manipulation for package and module based
filters), which required exposing some more endpoints to Move's parser.

## Test Plan

Existing E2E tests for events pagination:

```

sui-graphql-e2e-tests$ cargo nextest run \
  -j 1 --features pg_integration         \
  -- event_connection/
```

Plus new unit tests for `type_filter` module:

```
sui-graphql-rpc$ cargo nextest run -- type_filter
```
