This CL fix an issue related to tiering the maxBufferSize and
maxStorageBufferBindingSize limits. In detail, this CL:
1. Fix the maxStorageBufferBindingSize tiers to [128MB, 1GB, 2GB-4,
4GB-4] instead of the original last two 2GB-1 and 4GB-1, holding the
guarantee that maxStorageBufferBindingSize is a multiple of 4 bytes.
2. Add a maxBufferSize tier 4GB, ensuring the guarantee that
maxStorageBufferBindingSize must be no larger than maxBufferSize in
case of it tiered to 4GB-4. Previously the largest maxBufferSize tier
is 2GB, making this guarantee broken after tiering.
3. Move the adapter limits normalization logics in adapter initializing
to Limits.cpp to allow unittest. Related unittests implemented.
4. Normalize tiered limits to ensure that tiered
maxStorageBufferBindingSize and maxUniformBufferBindingSize are no
larger than tiered maxBufferSize. Related unittests implemented.
