raft: replace StatusWithoutProgress with BasicStatus
...
Now that a Config is also added to the full status, the old name
did not convey the intention, which was to get a Status without
an associated allocation.

raft: return non-nil Inflights in raft status
...
Recent refactoring to the String() method of `Progress` hit an NPE
because we return nil Inflights as part of the Raft status. Just
fix this at the source and properly populate the Raft status instead
of teaching String() to ignore nil. A real Progress always has a
non-nil Inflights.

raft: extract 'tracker' package
...
Mechanically extract `progressTracker`, `Progress`, and `inflights`
to their own package named `tracker`. Add lots of comments in the
progress, and take the opportunity to rename and clarify various
fields.

raft: extract progress tracking into own component
...
The Progress maps contain both the active configuration and information
about the replication status. By pulling it into its own component, this
becomes easier to unit test and also clarifies the code, which will see
changes as etcd-io/etcd#7625 is addressed.
More functionality will move into `prs` in self-contained follow-up commits.

raft: add (*RawNode).WithProgress
...
Calls to Status can be frequent and currently incur three heap
allocations, but often the caller has no intention to hold on to the
returned status.
Add StatusWithoutProgress and WithProgress to allow avoiding heap
allocations altogether. StatusWithoutProgress does what's on the
tin and additionally returns a value (instead of a pointer) to
avoid the associated heap allocation. By not returning a Progress
map, it avoids all other allocations that Status incurs.
To still introspect the Progress map, add WithProgress, which
uses a simple visitor pattern.
Add benchmarks to verify that this is indeed allocation free.
