[vm] Cache arg descriptors used by stubs

This reverts commit c5d973d9428670aa35359704b1a36d0d1117d8d7 and
commit 5e77a23604185b1ed50214e9d4e7ed1c07119858 because
the later breaks hot reload constant rehashing which can't handle
constant set which include vm-isolate objects.

Instead we expand standalone cache to cache descriptors with
1 type argument and 0, 1 or 2 arguments. This covers all
descriptors used in stubs.

Fixes b/429384250

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).
