Support ABI cfg flag in codegen

[davidsemakula]

Summary

Part 3/3 and closes #2479

• [y] y/n | Does it introduce breaking changes?
• [y] y/n | Is it dependent on a specific version of cargo-contract or pallet-revive?

Description

• Updates ink! codegen/proc-macros to use the new ABI cfg options for generating ABI specific code (e.g. #[cfg(ink_abi = "sol")])
• Updates CI to run integration tests with the new cargo contract test subcommand that propagates the ABI specified in Cargo.toml into the build environment for tests
• Update infra for running ink crate ui tests to support passing the ABI via cfg flags

See #2479 for details about "crate-level ABI declaration"

• Part 2/3 - Add cargo contract test subcommand cargo-contract#2034
