[enhance](nereids) improve masking of user's password for ALTER USER and CREATE USER commands in audit logs

[iaorekhov-1980]

What problem does this PR solve?

This PR adds masking for users passwords for CREATE USER and ALTER USER commands.
The masked values will be stored in audit table and audit files instead of actual values.
The same functionality already exists for SET USER PASSWORD and SET LDAP_ADMIN_PASSWORD commands, so we other commands related to passwords should be masked as well.

Could you please include this PR into 4.x branches, please!
