Fix 64-bit UB in BinaryenLiteral

[dcodeIO]

Changes the storage type of type ids in BinaryenLiteral from int32_t to uintptr_t, matching Literal. The maximum storage size of type ids changed with the introduction of tuples, with their type id being the memory address of the canonicalized type vector.

Interestingly, the related check

binaryen/src/binaryen-c.cpp

Lines 48 to 49 in bced89d

	static_assert(sizeof(BinaryenLiteral) == sizeof(Literal),
	"Binaryen C API literal must match wasm.h");

did not catch this due to implicit struct alignment, and other tests did not notice because type ids typically do not grow to values larger than 32 bits.
