[stack-trace] Use single string builder instance for serialization

This CL changes ToString of stack frames to optionally take a
IncrementalStringBuilder instance. Instead of using one instance per
frame when serializing a stack trace, a single instance is now used.

This improves local stack serialization micro benchmarks by ~6%.
