This is a misused function, as it was called during query cache flush,
when the provider operation bits were meant to record if methods for a
certain operation has already been added to the method store.

This refactors OSSL_LIB_CTX to avoid using CRYPTO_EX_DATA. The assorted
objects to be managed by OSSL_LIB_CTX are hardcoded and are initialized
eagerly rather than lazily, which avoids the need for locking on access
in most cases.
Fixes#17116.

We should stop receiving child callbacks if we're about to free up
the child libctx. Otherwise we can get callbacks when the libctx is half
freed up.

If a provider doesn't have any child providers then there is no need
to attempt to remove them - so we should not do so. This removes some
potentialy thread races.

This mostly entails passing around a provider pointer, and handling
queries that includes a pointer to a provider, where NULL means "any".
This also means that there's a need to pass the provider pointer, not
just down to the cache functions, but also be able to get it from
ossl_method_store_fetch(). To this end, that function's OSSL_PROVIDER
pointer argument is modified to be a pointer reference, so the
function can answer back what provider the method comes from.
Test added.

This makes it possible to limit the search of methods to that
particular provider. This uses already available possibilities in
ossl_algorithm_do_all().

If two threads both attempt to load the same provider at the same time,
they will first both check to see if the provider already exists. If it
doesn't then they will both then create new provider objects and call the
init function. However only one of the threads will be successful in adding
the provider to the store. For the "losing" thread we should still return
"success", but we should deinitialise and free the no longer required
provider object, and return the object that exists in the store.

We were deferring the initial creation of the child providers until the
first fetch. This is a carry over from an earlier iteration of the child
lib ctx development and is no longer necessary. In fact we need to init
the child providers immediately otherwise not all providers quite init
correctly.
