Make codegen not cast between fnptrs.

When generating the proc tables for dawn_native and dawn_wire (for the
client), we were casting between function pointers with the C types and
function pointers with the internal types. This is UB and was caught by
UBSan.

Replace casts between function pointers by casts between types inside
the functions themselves.
