This adds ossl_method_store_remove_all_provided(), which selectively
removes methods from the given store that are provided by the given
provider.
This also adds the EVP specific evp_method_store_remove_all_provided(),
which matches ossl_method_store_remove_all_provided() but can also
retrieve the correct store to manipulate for EVP functions.
This allows us to modify ossl_provider_self_test() to do the job it's
supposed to do, but through clearly defined functions instead of a
cache flushing call that previously did more than that.
ossl_provider_deactivate() is also modified to remove methods associated
with the deactivated provider, and not just clearing the cache.

(cherry picked from commit 2e4d0677ea)
When evp_method_store_flush() flushed the query cache, it also freed
all methods in the EVP method store, through an unfortunate call of
ossl_method_store_flush_cache() with an argument saying that all
methods should indeed be dropped.
To undo some of the confusion, ossl_method_store_flush_cache() is
renamed to ossl_method_store_cache_flush_all(), and limited to do
only that. Some if the items in the internal ALGORITHM structure are
also renamed and commented to clarify what they are for.

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.

We should stop receiving child callbacks if we're about to free 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.

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.
