Wait on the semaphore outside the try to ensure Release isn't called if the wait times out. No need to serialize GetTokenAsync calls since Azure Identity already handles that in their implementation.

By caching DefaultAzureCredential, ManagedIdentityCredential, ClientSecretCredential, and WorkloadIdentityCredential objects, we can take advantage of token caching in the underlying Azure.Identity implementation.
This should particularly reduce token request rates in Managed Identity environments and eliminate or reduce instances of throttling from the managed identity token endpoint.
This would address #1495.
