celldb in-memory mode, stats for actors, perf counters, minor fix in rldp2 (#1164)
* getactorstats query for validator-engine-console

* celldb in-memory mode (--celldb-in-memory option)

* rldp2: bugfix - do not estimate speed while nothing is sent

* add simple ed25519 benchmark

* fix compilation errors of different platforms and move to c++20

* fix some warnings

* turn on TON_USE_ABSEIL for glibc 2.27 nix build
