Populate supported Vulkan limits from the backend

This commit also unifies the initialization process for Adapters.
InitializeImpl() initializes the actual backend adapter.
InitializeSupportedFeaturesImpl() checks base WebGPU features and
discovers additional supported features.
InitializeSupportedLimitsImpl() checks base WebGPU limits and
queries the adapter's maximum supported limits.

Some of these limits from the backend are still overriden in the
frontend because they are limited by internal Dawn constants.
