fix(fmgc): string stars with non-runway-specific approaches

[tracernz]

Fixes #[issue_no]

Summary of Changes

Couldn't string a STAR with a non-runway-specific approach e.g. ELRU2A to RNAV F at NZQN. This removes the STAR filtering for non-runway-specific approaches in the MCDU page, and allows stringing runway legs in the case where there is only one runway in the STAR.

IRL behaviour is unclear at this stage, and in trying to get a reference for this particular approach I found the IRL database for a particular airline actually doesn't have these approaches in it. We can revisit in future when we can get better references. I think there are three options I can foresee:

• these approaches are never in the IRL database, in which case we should filter them out entirely,
• these approaches are processed into multiple runway-specific approaches by the FMS database tools,
• works as-is here

Testing instructions

Check that NZQN RNAV F or G can be strung with ELRUV2A. Check that regular approach/STAR combos you're familiar with work okay.
