Add new DaoAuthenticationProvider constructor

Add a new constructor to the DaoAuthenticationProvider, which allows
providing a custom PasswordEncoder to prevent instantiation of the
default delegating PasswordEncoder in the default constructor.

This provides a way to instantiate the DaoAuthenticationProvider on JDKs
where the default delegating PasswordEncoder cannot be instantiated due
to limited JCE providers for compliance reasons (e.g., FIPS).

Closes gh-12874
