[WebAssembly] Update to the new names for the memory builtin functions.

The WebAssembly committee has decided on the names `memory.size` and
`memory.grow` for the memory intrinsics, so update the clang builtin
functions to follow those names, keeping both sets of old names in place
for compatibility.
