Migrate from Newtonsoft json serializer to System.Text.Json source generator version

[wieslawsoltes]

General Description

During memory profiling in search of memory leaks (#10051) I have found that Newtonsoft json allocates a lot of memory (1.9GB) during app startup (my wallets in total are 22 MB of json).

Maybe migrating to System.Text.Json source generator version would improve that. Also System.Text.Json source generator version is AOT friendly for publishing NativeAOT apps.

How To Reproduce?

1. Run app under memory profiler

Looking deeper it might not be all json serialize that is allocating

This is duplicate of #4223?

This might be solved by #10272
So we will wait for this until there will be a decision on that.

@wieslawsoltes #10272 merged. Can you check if this is still an issue?

[molnard]

I moved this to "Not now". I do not see the perspective.

Useful information thx for the record. Closing it to aggregate the problem into one issue. #4223
