* list "all" targets explicitly
* add missing targets
* add missing build flags
* add test-integration target
* show tests output
* use wmake test on CI
* update submodules for all targets (like Makefile)
* remove unused function Test-Administrator

The test is flaky when the reply timeout is too low.
Increasing the timeout makes it slow.

Move the test to the integration suite.
Having a higher timeout is fine there.

* reuse the generated test blockchain across tests
* copy ChainPack to ensure test isolation

This improves the speed from 10s to 4s.

The package tests timeout can be reduced to 5s:

    go test ./cmd/rpcdaemon/commands -count 1 --timeout 5s

Cache "go-build" containing cached build artifacts from the Go build system.
This saves up to:
  - 6 min on Linux (from 10 min to 4 min)
  - 3 min on macOS  (from 13 min to 10 min)
  - 7 min on Windows (from 27 min to 20 min)

Cache Windows deps (mingw, cmake).
This saves 6,5 min on Windows builds (from 20 min to 13,5 min)

* binary tree

* Binary commitment tree

* [erigon2] Bin tree support

* Point to latest erigon-lib
