It's only a code move, without functional changes.
This is in preparation to implementing the same path functionality
for flexbuffers objects.

* chore: Del and NUMINCRBY use json::Path
Also, fix various protocol bugs when we sent simple string
instead of sending bulk strings.
Fixed a typo in path.cc that lead to a data race bug.
Finally, flip the flag in regression tests to start covering json::Path code
and added test coverage for the data race bug

* chore: switch to self-built flatbuffers
This should solve the linker errors on MacOs build.

feat: a test with flat buffers
Also, add an experimental flag `--experimental_flat_json` that allows writing json objects as flat strings using
flexibuffers.
The experiment shows that `debug populate 100000 a 10 type json elements 30`
uses almost 3 times less memory than with native jsoncons objects.

Also update actions versions to Node 20.
This change allows dragonfly to be built on MacOs.
However, we still have multiple failing tests on MacOS.

* upload only failed test logs
* remove printing log names for passed tests
* print slow tests with --duration
* separate regression and unit logs for CI workflow
* feat(pytest): More types for seeder
Add more types to the seeder and refactor replication test

Example usage:
```bash
# Create a 2-node cluster
./cluster_mgr.py --action=create --replicas_per_master=1 --num_master=2
# Move (no migration) all slots to first node
./cluster_mgr.py --action=move --target_port=7001 --slot_start=8192 --slot_end=16383
# Fill data - like run memtier
# Migrate all slots to 2nd node. One could measure how long this step takes.
./cluster_mgr.py --action=migrate --target_port=7002 --slot_start=0 --slot_end=16383
```
The bug: crash when starting replica while saving
The problem: accessing the wrong allocator on snapshot class destruction as it was destructed not in the thread of the shard
The fix: call snapshot destructor when we finish snapshot on the correct thread

Specifically, allows expressions in the form of
`max($.objs[*].score`, i.e. where a function aggregates 0 or more values
produced by the path expression. The final value is passed to a PathCallback.
In case no matches are found, json null value is passed. In any case, the callback
is called exactly once for such expressions.
In addition, fixed a parser bug that does not allow fields after the bracketing expression.
Finally, introduced an utility function for easier parsing of json::Path.

* chore(transaction): Untie scheduling from multi status
Idea: We decide whether we have to schedule not based on our multi status (atomic multi), but solely based on the fact if COORD_SCHED is set
Goal: Being able to use ScheduleSingleHop()/Schedule() for multi transactions, and thus later allow single hop multi transactions

Fix linker dependencies - now dfly_core depends on jsonpath.
jsonpath does not depend on CompactObject anymore.

No functional changes are made.
This change is needed to allow traversal functionality that will mutate json object during the traversal.
