Misleading argument name `dest`

[smoelius]

There are several functions with an argument named dest, suggesting "destination". However, the argument is not the destination written to, but rather the value written to that destination. (An example appears below.)

Would you consider a PR to rename all such dest arguments to value?

storage_store_slot is an example:

solang/src/emit/storage.rs

Lines 39 to 49 in 032d73e

	/// Recursively store a type to storage for slot-based storage
	fn storage_store_slot<'a>(
	&self,
	bin: &Binary<'a>,
	ty: &Type,
	slot: &mut IntValue<'a>,
	slot_ptr: PointerValue<'a>,
	dest: BasicValueEnum<'a>,
	function: FunctionValue<'a>,
	ns: &Namespace,
	);

Here is an example of its use; note that the argument dest is elem.into():

solang/src/emit/polkadot/storage.rs

Lines 411 to 419 in 032d73e

	self.storage_store_slot(
	bin,
	elem_ty,
	slot,
	slot_ptr,
	elem.into(),
	function,
	ns,
	);
