az get-access-token: performance regression factor 10 between version 2.59 and version 2.64

### Describe the bug

with newer az versions (> 2.6x) we are suffering from **performance regression** with **factor 10,**
e.g. using "**az account get-access-token**" we have
Azure **CLI v2.64**, with responses taking **10-15 seconds**.
When using **CLI v2.59** or lower, the response time is **1-2 seconds**

We have traced this also via our company firewalls etc, and there are no indication the the infrastructure is blocking something.

Please note that also libraries (e.g. promptflow), which invoke "az account get-access-token" are affected and wont work, because some of them have a timeout specified for the az call with 10 sec, which then fails...
Actually promptflow did fail because it hits the timeout, because of the performance regression in azure cli.

### Related command

az account get-access-token

### Errors

az account get-access-token
CLI v2.64, responses takes 10-15 seconds
CLI v2.59, responses takes 1-2 seconds

regression, with factor 10.
Libraries using this call will fail with timeout.
