This patch implements "store and MSAA resolve" store operation on Metal drivers that don't support MTLStoreActionStoreAndMultisampleResolve with a workaround that does MSAA resolve in another render pass. Driver workaround is one type of Dawn Toggles. Dawn Toggles will include other optional optimizations and features that can be configured to use or not when we create Dawn Devices. As all Metal try bots don't need this toggle, to better test this patch on the try bots: 1. We add the support of forcing enabling a workaround when starting an Dawn end2end test so that we can test the workaround on the platforms where the workaround is disabled. 2. We add an optional parameter DeviceDescriptor to CreateDevice() so that we can custom the toggles the Dawn device should use. This patch also adds the support of querying toggle details from Instance and the names of the toggles in use from Device. These APIs are tested in the Dawn unittests added in this patch.
