unknown import: ethereum::ethereum.call has not been defined

[leoyvens]

Summary

This happens when a file data source handler uses contract calls directly or is in the same AssemblyScript file as other handlers which use contract calls. If the contract call is done by a different handler in the same file, this can be fixed by putting the file data source handler in its own file, which is best practice.

Potential Fix

Contract calls in file data source handlers could be enabled by somehow passing the ethereum.call host fn when instantiating an offchain data source, relevant code:

graph-node/runtime/wasm/src/host.rs

Lines 137 to 141 in 92670f2

	let host_fns = data_source
	.as_onchain()
	.map(|ds| runtime_adapter.host_fns(ds))
	.transpose()?
	.unwrap_or_default();

This is still relevant - @leoyvens does this fail at build-time or at runtime?
