[TopicUtils] Optimize MangleName(), DemangleName() and MangleType()

[caguero]

🦟 Bug fix

Continuing the improvements in TopicUtils, this patch optimizes MangleName(), DemangleName() and MangleType().

It replaces character-by-character string building with std::replace and adds a missing const reference to avoid copying each string.

The benchmarks show that the new functions (the ones with the 2 suffix improve the original ones).
