[eslint] Add rules for consistent type imports

[mpodwysocki]

We should enable the following ESLint rules:

• Consistent Type Imports

The default for consistent type imports should separate the type imports from the regular imports such as the following:

import type {
  CommonClientOptions,
  OperationOptions,
  InternalClientPipelineOptions,
} from "@azure/core-client";
import { bearerTokenAuthenticationPolicy } from "@azure/core-rest-pipeline";
import type { TokenCredential } from "@azure/core-auth";
import type { TracingClient} from "@azure/core-tracing";
import { createTracingClient } from "@azure/core-tracing";

this has been added in October.
