Pauli 0090e50890 provider: flush the store cache when providers are loaded/unloaded.
When the providers change, the method cache needs to be flushed.  This also
impacts the cache is full partial flushes and the algorithm flushing by ID.

A new function is introduced to clear all of the operation bits in all
providers in a library context.

Fixes #15032
