Testing instructions

For both A32NX & A380X:

1. Select an ILS approach in the MCDU.
2. Once in the air and with approach phase active, press the APPR mode on the FCU without the "LS" button pressed on the EFIS control panel.
3. Amber "ILS" (A32NX)/ "LS"(A380X) should blink on the bottom right of the PFD and then stop after 9 seconds.
4. Once LS button is pushed on the associated side, the amber indication disappears

How to download the PR for QA

Every new commit to this PR will cause new A32NX and A380X artifacts to be created, built, and uploaded.

1. Make sure you are signed in to GitHub
2. Click on the Checks tab on the PR
3. On the left side, find and click on the PR Build tab
4. Click on either flybywire-aircraft-a320-neo, flybywire-aircraft-a380-842 (4K) or flybywire-aircraft-a380-842 (8K) download link at the bottom of the page

Aircraft Version
Stable

Build info
"v0.12.0"
Describe the bug
When doing an ILS approach in the A380, and the LS P/B's on EFIS is not turned ON, the LS will constantly flash in amber which is correct, but doesn't automatically display the lateral and vertical deviation scales when LOC or APPR Mode is armed.

Expected behavior
If LS P/B isn't selected when doing an ILS approach, it would automatically display the LOC and G/S deviation scales on both PFD's after arming the LOC P/B or APPR P/B, and the LS P/B's would automatically light up.
Landing System Scales

Steps to reproduce
Setup an ILS approach anywhare you want and conduct approach.
leave LS P/B's off.
Check that amber LS is flashing when getting nearer to runway.
ARM LOC P/B - and check that LS deviation scales automatically appear, and LS P/B lights up on both EFIS.
Deselect LOC
Also turn off LS P/B's on both EFIS.
Check that amber LS is flashing when getting nearer to runway.
ARM APPR P/B - and check that LS deviation scales automatically appear, and LS P/B lights up on both EFIS.

For A320 it's different.

The original purpose of this PR is to just add the LS indicator on the PFD. The automatic LS selection is left for future work and should be addressed in a further PR.
