For each assigned project, the worker sequentially calls
Sync_NetworkHalf and Sync_LocalHalf, respecting --local-only and
--network-only flags. To prevent scrambled progress bars, all stderr
output from the checkout phase is captured (shown with --verbose).
Result objects now carry status and timing information from the worker
for state updates.

Introduce the parallel orchestration framework for `repo sync
--interleaved`.
The new logic respects project dependencies by processing them in
hierarchical levels. Projects sharing a git object directory are grouped
and processed serially. Also reuse the familiar fetch progress bar UX.

Prepare for an interleaved fetch and checkout mode for `repo sync`. The
goal of the new mode is to significantly speed up syncs by running fetch
and checkout operations in parallel for different projects, rather than
waiting for all fetches to complete before starting any checkouts.

With a large number of sync workers, the sync process may fail on
macOS due to connection errors. The root cause is that multiple
workers may attempt to connect to the multiprocessing manager server
at the same time when handling the first job. This can lead to
connection failures if there are too many pending connections, exceeding
the socket listening backlog.

The command _PostRepoFetch will try to self update
during repo sync. That is beneficial but adds
version uncertainty, fail potential and slow downs
in non-interactive scenarios.
Conditionally skip the update if env variable
REPO_SKIP_SELF_UPDATE is defined.
A call to selfupdate works as before, meaning even
with the variable set, it will run the update.

Background:
- Manifest object is large (for projects like Android) in terms of
serialization cost and size (more than 1mb).
- Lots of Project objects usually share only a few manifest objects.
Before this CL, Project objects were passed to workers via function
parameters. Function parameters are pickled separately (in chunk). In
other words, manifests are serialized again and again. The major
serialization overhead of repo sync was
O(manifest_size * projects / chunksize)
This CL uses following tricks to reduce serialization overhead.
- All projects are pickled in one invocation. Because Project objects
share manifests, pickle library remembers which objects are already
seen and avoid the serialization cost.
- Pass the Project objects to workers at worker intialization time.
And pass project index as function parameters instead. The number of
workers is much smaller than the number of projects.
- Worker init state are shared on Linux (fork based). So it requires
zero serialization for Project objects.
On Linux (fork based), the serialization overhead is
O(projects) --- one int per project
On Windows (spawn based), the serialization overhead is
O(manifest_size * min(workers, projects))
Moreover, use chunksize=1 to avoid the chance that some workers are idle
while other workers still have more than one job in their chunk queue.
Using 2.7k projects as the baseline, originally "repo sync" no-op
sync takes 31s for fetch and 25s for checkout on my Linux workstation.
With this CL, it takes 12s for fetch and 1s for checkout.

With 551285fa35, the comment about number
of workers no longer stands - dict is shared among multiprocesses and
real time information is available.
Using 2.7k projects as the baseline, using chunk size of 4 takes close
to 5 minutes. A chunk size of 32 takes this down to 40s - a reduction of
rougly 8 times which matches the increase.

The current logic to create checkout layers doesn't work in all cases.
For example, let's assume there are three projects: "foo", "foo/bar" and
"foo-bar". Sorting lexicographical order is incorrect as foo-bar would
be placed between foo and foo/bar, breaking layering logic.
Instead, we split filepaths based using path delimiter (always /) and
then use lexicographical sort.

If a repo manifest is updated so that project B is placed within a
project A, and if project A had content in new B's location in the old
checkout, then repo sync could break depending on checkout order, since
B can't be checked out before A.
This change introduces checkout levels which enforces right sequence of
checkouts while still allowing for parallel checkout. In an example
above, A will always be checked out first before B.
