Make deno_cli installable via crates.io (#2946)

- Fixes cargo publish on deno_typescript, deno_cli_snapshots, and
  deno_cli.
- Combines cli_snapshots and js into one directory.
- Extracts TS version at compile time rather than runtime
- Bumps version awkwardly - it was necessary to test end-to-end
  publishing. Sorry.
- Adds git submodule deno_typescript/typescript

 This is a small crate which exports just a few static blobs. It contains a
 build.rs file which compiles Deno's internal JavaScript and TypeScript code
 first into a single AMD bundle, and then into a binary V8 Snapshot.
 
 The main Deno executable crate ("cli") depends on this crate and has access to
 all the runtime code.
