Ability to skip type checking of remote modules

[dsherret]

The TS compiler has a --skipLibCheck compiler option that allows skipping type checking of declaration files.

Similarly, it might be nice for Deno to:

1. Have a way to not type check the private implementations of remote modules or make this the default (this would help with compile times too).

2. Have something like the --skipLibCheck compiler option that skips type checking of remote modules completely or have a way to do this on a case-by case basis. Example, in deps.ts people could add a comment above the import:

   // @ts-skip-check
   export * as myProject from "https://deno.land/x/my-project/etc....";
   

The reason why this would be nice is because remote modules are often out of our control and we might want to depend on an old version of a dependency that now has type checking errors in the current version of the TS compiler being used.

I suggest something like:

    --no-check=<all|remote|none|<blacklist>...>
        Skip type checking for the specified modules (default: remote)

(The "default" is chosen when the option isn't given. If it is given, it requires a value.)

@kitsonk what's your take on this issue?

It seems like a lot of work which would cause a level of confusion. I think we should land the binary capability to skip type checking and live with that for a while before making the whole thing more complicated.

So --no-type-check flag that has global effect 👍 makes sense for a first pass

--no-check option landed in #6456, will be released in v1.2.0
