Optimize code for performance

[blikblum]

This PR do various optimizations:

• Avoid creation of temporary arrays in sanitizeChildren
• Use a hash map instead of Array.includes to check for vnode and svg
• Short circuit in considerData and considerKey when there is no data or key properties
• Call sanitizeText once per createElement call

It keeps the same general structure of the code

These are the benchmark numbers after the optimizations:
