[wasm][debugger] Improve debugger performance based on JMC (#86982)

* Improve debugger performance.

* Loading assembly bytes if JMC is disabled after the debugger session is started.

* Fix CI.

* Load symbols on demand if JMC is enabled, we don't need to spend a lot of time loading information from 149 assemblies if we will probably not need all of them.

* Impriving the performance sending only metadata and not the full assembly.

* Fixing compilation error on tvos

* Apply suggestions from code review
