Deprecate |BN_mod_exp_mont_word| and simplify its implementation.

|BN_mod_exp_mont_word| is only useful when the base is a single word
in length and timing side channel protection of the exponent is not
needed. That's never the case in real life.

Keep the function in the API, but removes its single-word-base
optimized implementation with a call to |BN_mod_exp_mont|.
