Move Type-related functions into Type class (NFC) (#2556)

Several type-related functions currently exist outside of `Type`
class and thus in the `wasm`, effectively global, namespace. This moves
these functions into `Type` class, making them either member functions
or static functions.

Also this renames `getSize` to `getByteSize` to make it not to be
confused with `size`, which returns the number of types in multiple
types. This also reorders the order of functions in `wasm-type.cpp` to
match that of `wasm-type.h`.
