Add OSSL_PARAM_construct_from_text() and OSSL_PARAM_allocate_from_text()

Add OSSL_PARAM_construct_from_text() and OSSL_PARAM_allocate_from_text()

These are utility functions that can be used to replace calls to
ctrl_str type functions with get_params / set_params types of calls.
They work by translating text values to something more suitable for
OSSL_PARAM, and by interpretting parameter keys in a compatible
fashion.
