A0-4233: Nightly workflow for feature-gated builds (#1672)

# Description

This PR adds a simple `cargo check` command for `try-runtime` and
`runtime-benchmarks` builds. Although it takes < 10 minutes, it is
enough to build it in nightly or on demand only.

## Type of change

- New feature (non-breaking change which adds functionality)
