Enforce DataModel::Provider everywhere (#36319)

* Pass 1: remove a large set of ifdefs * More flags removes * Remove more flags * More flags removes * Clean up a few more builders * Clean up references from ember compatibility functions and make the data model implementation of reporting and attribute path expand iterator be the only implemented versions * Remove ServerClusterCommandExists * Remove ConcreteAttributePathExists * Remove ReadSingleClusterData * Remove GetAttributeMetadata * Even more cleanup * Remove invalid include * Update target test file: we removed all DM enable/disable * Add back endif * Cleanup targets for building * Cleanup unused target * one more unused function removal * Fix up one condition * Restyled by clang-format * Update src/app/AttributePathExpandIterator.h Co-authored-by: Boris Zbarsky <[email protected]> * Update src/app/AttributePathExpandIterator.h Co-authored-by: Boris Zbarsky <[email protected]> * Update src/darwin/Framework/CHIP/ServerEndpoint/MTRServerAccessControl.mm Co-authored-by: Boris Zbarsky <[email protected]> * Add back missed code * Restyled by clang-format * Update src/app/tests/BUILD.gn Co-authored-by: Junior Martinez <[email protected]> --------- Co-authored-by: Andrei Litvin <[email protected]> Co-authored-by: Restyled.io <[email protected]> Co-authored-by: Boris Zbarsky <[email protected]> Co-authored-by: Junior Martinez <[email protected]>
