[WebAssembly] Change indices types to unsined int (NFC)

Browse Source 
Summary:
This changes int types to unsigned int in a few places: function indices
and `wasm::Valtype` (which is unsigend int enum).  Currently these
values cannot have negative values anyway, so this should not be a
functional change for now.
