fix: strlen is not constexpr

[proxict]

Defining the string literals as char arrays instead of letting them decay to pointers allows us to use sizeof instead of strlen() to get the length of string literals.

The project compiles with strlen() used in the constexpr context only thanks to compiler extensions, but it's not standard compliant.

@proxict did you check all usages of these strings also ?
Thanks for the pr!

I still want to go through the repository and replace strlen()s for these variables with sizeof. But I wanted to see the CI output first to make sure this commit doesn't break anything (I have tried a local build, but only for one platform).

I hope it's okay like that, it's my first PR to this project, I believe :-)

Pull request overview

This PR fixes a standards compliance issue by converting string literal declarations from pointers to arrays, enabling the use of sizeof instead of the non-standard strlen() in constexpr contexts.

• Converts all string literal declarations from const char* to const char[]
• Replaces strlen() with sizeof() - 1 for compile-time length calculation of T__gz

I just checked all occurrences of these variables and replaced strlen() with sizeof() - 1 where possible.
