When creating a console instance, one must pass "printFunc" arg
which is used internally by Console to output messages.
Due to numerous refactors there was a single method ("console.clear()")
that used "Deno.stdout" instead of "printFunc".
This commit unifies how "Console" outpus message, by using
"printFunc" in all methods; consequently "Deno.stdout" is no longer
imported in "cli/js/console.ts" making it a standalone module that doesn't
depend on any CLI-specific APIs.
1. Array elements are now grouped the same as in Node.js
2. Limit to 100 (Node.js default) elements to display in iterable
3. Print each element in new line if excessing max line length (same as in Node.js)
4. Print length of the TypedArray
5. Print information about empty items in Array
All Deno runtime test files were moved to cli/js/tests/ directory.
It makes a clear distinction that cli/js/tests/ contains code
that is run under Deno runtime as opposed to code in cli/js/ which
is used to create bundle and snapshot with "deno_typescript".
