[beta] Revert "[dap] Simplify URI handling in IsolateManager.addBreakpoint" and "[dds/dap] Add/remove breakpoints as required instead of replacing the whole set"

This is a cherry-pick of a recent commit that reverted two DAP changes because they resulted in leaking of breakpoints/scripts in the VM during reloads.

Issue description: Leaking objects in the VM during hot reloads
What is the fix: Revert the changes that triggered this issue
Why cherry-pick: To avoid this (newly-introduced) leak
Risk: Low, this is a simple revert putting code back to how it was previously for many years
Issue Link(s): See discussion in https://docs.google.com/document/d/1eeEHG3EL4D5EbB3YiAO5X2TcCRIciFMSPKL_hFGP0Gk/edit?disco=AAABk-csO5o

Original revert CL description:

This reverts two commits (in separate patch sets in the CL):

- commit 482a7caed773bb8e6655808db4384ac90d76d89b: [dap] Simplify URI handling in IsolateManager.addBreakpoint
- commit d0a7ef44595fc7ab2991c391c6cd0609b7688402: [dds/dap] Add/remove breakpoints as required instead of replacing the whole set

The first revert is to avoid conflicts while reverting the second, and will be reapplied later (likely after the release branch, since it is not critical to include). The second revert is because this change resulted in leaked Script objects in the VM.

There is an additional change (patch set 3) to fix up the changelog/versions so they don't go backwards.

Dart

An approachable, portable, and productive language for high-quality apps on any platform

Dart is:

  • Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.

  • Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
