Add functions to see if a provider is available for use.
Public function OSSL_PROVIDER_available() takes a library context and
a provider name, and returns 1 if it's available for use, i.e. if it's
possible to fetch implementations from it, otherwise 0.
Internal function ossl_provider_activated() returns 1 if the given
OSSL_PROVIDER is activated, otherwise 0.
To make this possible, the activation of fallbacks got refactored out
to a separate function, which ended up simplifying the code.
