[wasm] further simplification of WasmCompiledModule

[wasm] further simplification of WasmCompiledModule

Calculate memory size from the available heap. This avoids
the bugs due to some numbers being stored as objects (by-ref)
and thus needing special handling when cloning.

This leaves all the rest of the numbers as read-only.

Further simplified by representing globals size as a Smi.
