[vm/ffi] Implement FFI callbacks on AOT for ELF and Asm snapshots (excl. blobs).

To do this, we add writable data sections (currently uninitialzed) to ELF and Asm snapshots
and allow Instructions to have patchable relocations against (the start of) these sections.

Issue https://github.com/dart-lang/sdk/issues/37295 (see also for design & discussion).

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web

Dart has 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).
