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
