Moving V8 to only flat strings

- Cons strings in V8 are efficient for string addition but require flattening before use, adding complexity.
- Previous attempts to fix string concatenation issues include using overallocated buffers with dynamic string builders.
- A new proposal suggests using flat strings with geometrically growing buffers and fixed space at the start to avoid circular buffers.
- The proposal includes a high water mark (hwm) field in StringBuffer to optimize memory usage and GC efficiency.
- Benefits of the new approach include simplified string handling and potential performance improvements, but implementation success is uncertain.
