Fix compiling with abcipp and set up CI to check it

[james-chf]

ABCI 0.19 (formerly known as ABCI++) is coming in Tendermint v0.38 and will provide us with vote extensions, which was used by the original design of the Ethereum bridge. Code to do with it is guarded behind the abcipp flag, and --no-default-features should be used also. We should run CI to make sure that our ABCI 0.19 code continues to compile/pass tests.

Compiling with abcipp currently doesn't work on main or eth-bridge-integration branches (as of 2022-11-04). We should fix up in main first and have a CI job to at least cargo check it, then do the same for eth-bridge-integration.

• fix in main
