This change aims to keep versions of mockery consistent across developer laptops.

This change adds mockery to the `tools.go` file so that its version can be managed consistently in the `go.mod` file.

Additionally, this change temporarily disables adding mockery's version number to generated files. There is an outstanding issue against the mockery project related to the version string behavior when running from `go get`. I have created a pull request to fix this issue in the mockery project.

This changes adds an `MempoolError` field to the `ResponseCheckTx`. This will allow clients to understand that their transaction was rejected from the mempool despite passing the ABCI check. 

This change also updates the code to make use of early returns to prevent highly nested code blocks. Namely, it returns when the type assertion fails at the beginning of the method, instead of wrapping the entire method in a large if statement. This has a somewhat large effect on the diff as rendered by github.

There are many `//go:generate mockery` lines in the source code.
This change adds a make target to invoke these mock generations.
This change also invokes the mock invocations and adds the resulting mocks to the repo.

Closes #6551 

Simple PR to add the total gas used in the block by adding the gas used in all the transactions. 
This adds a `TotalGasUsed` field to `coretypes.ResultBlockResults`.

Its my first PR to the repo so let me know if there is anything I am missing!

@fedekunze In case you want to take a look

Remove `Context` from the `TxInfo` type and instead require the caller to pass a `Context` to `CheckTx` which is idiomatic.

i.e. without double pointer. With double pointer, it was possible to
submit `null` value, which will crash the server.
