  [WGSL] Add support for binary and unary expressions with packed types

Reviewed by Dan Glastonbury.

Build onto PR#14736 and extend the support for packing/unpacking in binary and
unary expressions. Since not all binary and unary expressions are allowed on packed
types, we assume these expressions can only be performed on unpacked types. We
unpack the operand(s) and their result is always unpacked.
