fix: Fix wrong reallocations in String#replaceAll + refactoring - #1564

I find it a little hard to grasp the variable names in this function. Would you be OK with making these a little more self explaining while on it? For example

• len -> thisLen
• slen -> searchLen
• rlen -> replaceLen
• size -> outSize
• resLen -> outLen
• chunk -> ?

Great to see this fixed so quickly, thanks @MaxGraey

Just out of curiosity, what is the development / debug experience for the core AssemblyScript libraries? Is it possible to step through, inspect, or perhaps just log, when trying to resolve these errors?

wasm pretty hard to debug especially on node.js. I usually use trace and assert buiiltin functions. For very hard cases - just reproduce same code on ts/js and debug as usual)
