FIX: Use the invariant culture for capitalization when generating code

[K-Tone]

Description

A customer with the Turkish locale set, noticed that when we're generating function names for Input Actions, we're using the wrong function. This way, the "info" input action results in Onİnfo method name (notice the dot above the I, it's apparently how the capital for i looks like in Turkish).

Glanced at the draft PR and I would just like to suggest to (if possible) get some unit test in that could catch any problems with culture info.

Also I see that some tests are failing due to compilation issues apparently, fixing that in a moment.

The changes look good to me. Many thanks for going through all the cases!

The PR is still a draft, so this is probably still in work, but just a changelog and a link to a Jira ticket is missing in my POV.
