Forward declare operator overload (components/)

When building using jumbo, files get merged and more options
are presented for the compiler. When using the operator overload <<
in PasswordRequirementsSpec, the compiler gets too many
options and will fail before reaching the correct operator overload.

The issue solved by forward declaring the operator overload in the files
that uses it.
