reorg: move js runtime tests to cli/js/tests/ (#4250)

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".
