- Current API in ConfigurationManager makes it very hard to provide spec-mandated per-device SPAKE2+ parameters (verifier, salt, iteration counts) and discovery discriminator, since it expects "in-app" common SDK handling of the data for something that actually usually comes from the factory. This PR does the following: - Adds CommissionableDataProvider interface, of which an instance is known to the ConfigurationManager. - Adds a legacy path to avoid requiring setting a CommissionableDataProvider in the short term - A linux implementation of CommissionableDataProvider showcasing providing externally generated SPAKE2+ verifier/salt/iterations - Refactoring of all direct usage of ConfigurationManager to get discriminator/SPAKE2+ parameters Testing done: - Cert tests still pass with no change - All unit tests still pass, including those modified - Setting GN arg `chip_use_transitional_commissionable_data_provider=0` properly causes targets that don't provide an implementation from running. - Manually verified the new Linux command-line arguments to all-clusters-app allow passing custom version of verifier or iteration counts. Fixes #15543
