{Identity} Support UsernamePasswordCredential.authenticate

[jiasli]

Description
Due to the removal of UsernamePasswordCredential.authenticate, when username+password is used as the authentication method, Azure CLI can't persist user's AuthenticationRecord and utilize refresh tokens stored in MSAL cache. In such case, Azure CLI will have to save user's password by itself, which is absolutely not a good idea from a security perspective. See Azure/azure-sdk-for-python#11449, Azure/azure-sdk-for-python#11546

This PR solves the above issue by incorporating the changes from Azure/azure-sdk-for-python#11528

⚠ However, using this AuthenticationRecord correctly remains unsolved: Azure/azure-sdk-for-python#11448. We use InteractiveBrowserCredential as a temporary workaround:

azure-cli/src/azure-cli-core/azure/cli/core/_identity.py

Lines 292 to 293 in 595646e

	return InteractiveBrowserCredential(authentication_record=auth_record, disable_automatic_authentication=True,
	enable_persistent_cache=True)
