Proposal: programs' frame_system::AccountInfo permanent existence

[breathx]

Motivation of the PR is to increase transparency of the system and isolate user-space from executable environment's restrictions, with upcoming security improvement and bug-safe space within the substrate code.

Invariant: Each program should have ED locked on its account when active.

Implementation details (TODO):

• Implement charging from balance within pallet_gear::upload_program and pallet_gear::create_program extrinsics
  • 2 tests
• Implement charging from program balance on backend level in case of calling gr_create_program and further charging in JournalNote::StoreNewPrograms processing (track the case when code not exist, so refund should be performed)
  • 2 tests
• In case of calling gr_exit this funds should be unlocked and transferred to inheritor
  • 1 test
• Remove value limits (check_value) for sendings in all send-extrinsics and all backend send-syscalls
  • 2 tests: extrinsics/syscalls (for syscalls could be implemented in core-processor/ext units)
• Replace all transfers in system to Existence::AllowDeath version
• Implement migrations that transfer ED from treasury for each existing program
  • try-runtime tests that after migrations all program that are in "Active" status has ED locked.
• Fix existing tests

---

• Consider (maybe only open an issue or resolving in another PR) to lock the balance for builtin actors and "pallet_gear_staking_rewards" and "pallet_gear_bank"
