Add bridges list in genesis config (fixes #515)

[Nutomic]

Summary of changes
Changes introduced in this pull request:

• Adds bridges parameter to bridge-registry GenesisConfig which allows adding bridges at build time
• Add a testing bridge in testnet_genesis() chainspec
• Fix for crash in submitProposals.ts (@shekohex)
• Use existing ResourceId struct instead of typedef
• Use cargo run in scripts/run-standalone.sh instead of executing binary, so that separate build step is not necessary
• Extract some constants from chainspec code

Reference issue to close (if applicable)

Closes #515

[Nutomic]

Here are the bridge parameters being passed in. This works and shows up as expected in polkadot web ui.

However the test case in tangle-network/relayer#355 is failing now with Metadata(IncompatibleStorageMetadata("BridgeRegistry", "Bridges")), I think its necessary to update the dependency in webb-rs crate to fix it.

Yup, this needs an Update to webb-rs, can you generate the new metadata locally and use the local version of webb-rs to test that?

[Nutomic]

I did that according to instructions, files src/substrate/dkg_runtime.rs and src/substrate/protocol_substrate_runtime.rs got updated. I changed the relayer webb dependency to use the local repo path, however its still giving the same error. Not sure what Im missing.

Edit: managed to fix this

[shekohex]

Needs to fix the CI, and this good to be merged!
