wasm: support and optimize for all packed unions
For packed unions where its abi size is less than or equal to 8 bytes
we store it directly and don't pass it by reference. This means that
when retrieving the field, we will perform shifts and bitcasts to ensure
the correct type is returned. For larger packed unions, we either allocate
a new stack value based on the field type when the field type is also passed
by reference, or load it directly into a local if it's not.
