feat(a380x/fcu): Fix visual issues with FCU light test and missing labels

[heclak]

Fixes #9091

Summary of Changes

• Update display values on the FCU for the light test to match the reference image
• Change decimal point width in FCU font to match font and display in reference. This fixes the overlapping text issue in the speed display. This replaces an older PR #9129
• Move the FPA label to the left of the V/S label as per reference
• Add TRUE label. The label is not yet connected to TRUE mode but appears in the light test. Will be connected in a separate PR
• Move the degree symbol closer to the speed value to match the reference
• Changed first digit of FPA/VS to include different test digit (includes a +- symbol within the 8)
• Change FPA to not use the left most +- character. FPA +- will be aligned under the "F" character
• Add test pattern for EFIS CP labels

Testing instructions

1. Set ANN LT sw to TEST. Check indication on FCU matches references and updated screenshots.
2. Switch modes on the FCU to check that labels are displaying/hiding correctly outside of TEST mode. Change numbers on FCU.
3. Check that preselect baro setting functions correctly. Preselect should timeout after a short time when in STD mode.

FCU updates are complete for this PR. TRUE indication will be done in another PR due to some refactoring of the heading indication that will be done at the same time.
