Ambiguous overload errors with wxWidgets 3.2.4

[onitake]

Description of the bug

PrusaSlicer fails to compile with wxWidgets 3.2.4, due to the introduction of initializer list constructors in wxArrayString.

Upstream issue: wxWidgets/wxWidgets#24093
They mention that the changes were intentional and won't be pulled back, so changes will be needed in the PrusaSlicer source code.

This bug was discovered during the last Debian package rebuild: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1056897

I've posted a simple patch that adds explicit std::vector intermediates, but it would probably be better to refactor the source code. The wxWidgets developers apparently want to deprecate wxArrayString and other convenience types, as mentioned here: wxWidgets/wxWidgets@4d62df4
I can submit the patch as a PR if needed.
Refactoring may result in breaking changes, so it's probably better to hold off until the next major wxWidgets release.

Project file & How to reproduce

1. Compile PrusaSlicer against wxWidgets 3.2.4 or newer (tested with gcc 13.2.0)
2. Failure:
