enhancement: compare fuel-indexer and forc-index versions

[lostman]

Description

Closes #1377.

This PR embeds TOOLCHAIN_VERSION in the indexer's WASM module and adds a check when the indexer is deploys which only permits the indexers whose TOOLCHAIN_VERSION matches the fuel-indexer version.

Testing steps

CI tests should pass.

Manual testing:

1. Start fuel-indexer:

cargo run -p fuel-indexer -- run --fuel-node-host beta-4.fuel.network --fuel-node-port 80 --replace-indexer

2. Create and deploy an indexer using an older version of forc-index:

forc-index --version
forc index 0.20.11

forc-index new /tmp/test-indexer
forc-index deploy --path /tmp/some-indexer

{
  "details": "WASM module toolchain version `unknown` does not match fuel-indexer version `0.21.1`",
  "success": "false"
}

Additionally, run fuel-indexer with --disable-toolchain-version-check to be able to deploy the above indexer anyway.

3. Deploy one of the indexers in the repository (hence, using the same toolchain version):

cargo run --bin forc-index -- deploy --path examples/fuel-explorer/fuel-explorer/
