feat: contracts and project providers + cleanup

[harrysolovay]

Resolves #626

This PR introduces two new providers:

1. A ProjectProvider, which allows easy use within a substrate project. Simply capi -- deno run -A my_script.ts in your Substrate project.

my_script.ts

import { MyCustomPallet } from "http://localhost:4646/frame/project/@latest/mod.ts"
import { assertEquals } from "https://deno.land/std/testing/asserts.ts"

Deno.test("works", async () => {
  assertEquals(expected, await MyCustomPallet.item.run())
})

2. A contracts provider, which wraps substrate-contracts-node (per the request of @wottpal).

import { ... } from "http://localhost:4646/frame/contracts_dev/@latest/mod.ts"

This PR also...

• extracts common provider functionality into an abstract FrameBinProvider class
• changes the shape in which provider factories are passed to Env
• improved implementation of test provider launch timeouts

Next up: #649

substrate-contracts-node does not emit a author_extrinsicUpdate finalized event with result: { finalized: "0x..." }

Perhaps, for instant finality, the inBlock event should be the terminal transaction status.

The following is a work around for local debugging

@kratico thank you for the extraordinary contracts fix! The contracts example now executes in less than a second!

We can re-add the toggling on/off when we tackle a comprehensive approach to logging from the Capi server (perhaps using Logger from deno_std). I plan to take a pass at this in a PR that also addresses #649.

Just for reference, this would probably also fix this implicitly: paritytech/substrate-contracts-node#160
