auth/credentials: add cli_credentials_set_utf16_password()

We need a way to initialize the cli_credentials from the raw utf16 blob,
which might not be completely valid utf16, which means the conversion
from CH_UTF16MUNGED to CH_UTF8 might loose information.

This would result in an invalid nt_hash, when we convert back
from CH_UTF8 to CH_UTF16LE.
