Resolves #1705 This PR adds the Deno APIs as a global namespace named `Deno`. For backwards compatibility, the ability to `import * from "deno"` is preserved. I have tried to convert every test and internal code the references the module to use the namespace instead, but because I didn't break compatibility I am not sure. On the REPL, `deno` no longer exists, replaced only with `Deno` to align with the regular runtime. The runtime type library includes both the namespace and module. This means it duplicates the whole type information. When we remove the functionality from the runtime, it will be a one line change to the library generator to remove the module definition from the type library. I marked a `TODO` in a couple places where to remove the `"deno"` module, but there are additional places I know I didn't mark.

// We want to test many ops in deno which have different behavior depending on
|
|
// the permissions set. These tests can specify which permissions they expect,
|
|
// which appends a special string like "permW1N0" to the end of the test name.
|
|
// Here we run several copies of deno with different permissions, filtering the
|
|
// tests by the special string. permW0N0 means allow-write but not allow-net.

// See tools/unit_tests.py for more details.
