[WIP]expression: support ValidatePasswordStrength()

[wjhuang2016]

What problem does this PR solve?

Support ValidatePasswordStrength() except checking by a dictionary file, See #9741 or #2632

What is changed and how it works?

Accroding to https://dev.mysql.com/doc/refman/8.0/en/validate-password-options-variables.html
and https://dev.mysql.com/doc/refman/8.0/en/encryption-functions.html#function_validate-password-strength, we need to check the password strength by user 、auth_user、length 、mixed_case_count、number_count 、special_char_count, even a dictionary file.
Presently I check the above conditions except dictionary file, and I'm not sure whether we can read a file directly in a distributed environment.

In MySQL, a user can decide whether to use validate_password component. If we apply the valide_password before setting a password, we may need a option for user to decide whether to check
password by valide_password.
