Support `get_token_info` protocol in AAZ

[jiasli]

Is your feature request related to a problem? Please describe.
AAZ currently still uses the old get_token protocol:

azure-cli/src/azure-cli-core/azure/cli/core/aaz/_http_policy.py

Line 80 in 4826c98

self._token = self._credential.get_token(*self._scopes)

Describe the solution you'd like
AAZ should use the new get_token_info protocol.

Describe alternatives you've considered
Use Azure CLI's internal acquire_token protocol (#29955) to decouple from Azure SDK.

Additional context

• Support get_token_info protocol #29967
• {Core} Decouple MSAL credentials from SDK get_token protocol #29955
