tools: remove mockery from tools.go (#9196)

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](https://github.com/tendermint/tendermint/blob/10e1ac8feabd8ce7fd560ebecb11b929376fcb9c/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.
