Implement and test a module that prints the different help messages (global, per task, subtasks)

[kanej]

This is a v-next task to implement the help feature of Hardhat cli tasks.

For the moment we are only supporting --help and not help as its own task, so:

Global

> hardhat --help
Hardhat version 2.22.5

Usage: hardhat [GLOBAL PARAMETERS] <TASK> [TASK PARAMETERS]

GLOBAL PARAMETERS:

  --config              A Hardhat config file.
  --version             Shows hardhat's version.

AVAILABLE TASKS:

  console               Opens a hardhat console
  run                   Runs a user-defined script after compiling the project
  help                  Prints this message

Per Task

> hardhat run --help
Hardhat version 2.22.5

Usage: hardhat [GLOBAL PARAMETERS] run script

POSITIONAL ARGUMENTS:

  script        A js file to be run within hardhat's environment 

run: Runs a user-defined script after compiling the project

For global options help run: hardhat help

Per subtask
