Avoid using dynamically allocated vector for punctuators_and_operators

[codeinred]

I'm currently working on a memory profiler, and I noticed that 880 bytes was always being allocated at the start of any program that I tested. This allocation was due to punctuators_and_operators, inside cpptrace.

I've created this MR to convert punctuators_and_operators into a statically allocated array, so that cpptrace doesn't do any allocations on initialization.

decalre the array as static and constexpr otherwise it will be reconstructed everytime on the stack

@ZXShady this array is a global constant. It’s namespace-scope. Some older compilers don’t support constexpr std::string_view, and that’s why i didn’t use constexpr here. if you look at the surrounding arrays, none of those are declared constexpr either

my bad, thought it was function local
