ISO C++11 warnings for constexpr modifier on mvkGetReportingLevelString()

[SRSaunders]

Adding constexpr to mvkGetReportingLevelString() results in many clang warnings.

ISO C++11 does not allow conversion from string literal to 'char *'

I am using Ventura 13.6.6 with Xcode 15.2

Yeah. Sorry That was my bad. That's what I get for using GitHub UI to change code functionality!

I should have just pulled your code in and tested locally to see if it warranted any mods.

Sorry for introducing the confusion. 🤦🏻‍♂️

And thanks for aiming to fix it!

[SRSaunders]

No worries, thanks for fixing.
