oss-directory: create a tag for `ANY_EVM` in the network enums

[ccerv1]

What is it?

We should have a tag that instructs the indexer to look for deployments on any EVM chain on OSO. This is preferable to enumerating them individually. It's also preferable to assuming any deployer should show up on all chains as this might not always be the case and we don't want to hardcode into the schema.
