Create pr-check workflow

[chris3ware]

pr-check workflow combines pr-title and wait-for-checks in downstream repositories. Combining the jobs into a single workflow ensures pr-title succeeds before 'checks' runs removing the need for the empty commit.

This has the added benefit of the required check workflow name being the same in the iac configuration.

To have consistent required check name between workflow repo and all calling repos an input can be used to skip running checks when called.

Not required. Have combined pr-title and checks into pr-check - the same as other repos. See #172
