* Performance improvements for the event query API (#7319)
Rework the implementation of event query parsing and execution to
improve performance and reduce memory usage.
Previous memory and CPU profiles of the pubsub service showed query
processing as a significant hotspot. While we don't have evidence that
this is visibly hurting users, fixing it is fairly easy and self-contained.
Updates #6439.
Typical benchmark results comparing the original implementation (PEG) with the reworked implementation (Custom):

The `mockery` project recommends against using a binary of `mockery` that has been created using `go install`. https://github.com/vektra/mockery/pull/456. Developers of Tendermint wishing to generate mocks should avoid having a version of `mockery` on their path that does not match the version listed in [mockery_generate.sh](10e1ac8fea/scripts/mockery_generate.sh (L11)). To make this easier for developers, the `mockery_generate.sh` script uses a containerized copy of `mockery` if `mockery` is not present on the developer's `PATH`. This containerized version of `mockery` uses the same version of mockery as our CI pipelines and allows all developers to automatically use the same version without having to manage it themselves.

A workaround for #6729. Add parameters to control buffer sizes for
event subscription RPC clients. On some networks, buffering causes
clients to be dropped and/or events to be lost.
For additional context, see the discussion on #7188.
- Add experimental_subscription_buffer_size config parameter
- Add experimental_websocket_write_buffer_size config parameter
- Add experimental_close_on_slow_client config parameter

This change backports the PostgreSQL indexing sink, addressing part of #6828.
Development on the main branch has diverged substantially since the v0.34.x
release. It includes package moves, breaking API and protobuf schema changes,
and new APIs, all of which together have a large footprint on the mapping
between the implementation at tip and the v0.34 release branch.
To avoid the need to retrofit all of those improvements, this change works by
injecting the new indexing sink into the existing (v0.34) indexing interfaces
by delegation. This means the backport does _not_ pull in all the newer APIs
for event handling, and thus has minimal impact on existing code written
against the v0.34 package structure.
This change includes the test for the `psql` implementation, and thus updates
some Go module dependencies. Because it does not interact with any other types,
however, I did not add any unit tests to other packages in this change.
Related changes:
* Update module dependencies for psql backport.
* Update test data to be type-compatible with the old protobuf types.
* Add config settings for the PostgreSQL indexer.
* Clean up some linter settings.
* Hook up the psql indexer in the node main.
