These functions are prerequisites for implementing EVP_PKEY_todata().
OSSL_PARAM_dup() is required to make a deep copy of the exported
params (since the provider export() uses a OSSL_PARAM_BLD which throws away the
data after the call), and then use OSSL_PARAM_merge() to add some additional params
that can be passed to the EVP_PKEY_todata().

POSIX mandates that time_t is a signed integer but it doesn't specify the
lenght. Having wrappers lets uses ignore this.

Prior to this, the param builder had a statically sized array internally.
This changes it so that it uses a stack instead.

Since this is public, it is best to make the underlying structure opaque.
This means converting from stack allocation to dynamic allocation for all
usages.

The catalyst for this is the difficult of passing BNs through the other
OSSL_PARAM APIs.

A fuller implementation of PARAMS_TEMPLATE as per #9266 but renamed.
This introduces a statis data type which can be used to constructor a
description of a parameter array. It can then be converted into a OSSL_PARAM
array and the allocated storage freed by a single call to OPENSSL_free.
