This change mostly aims to get OpenCensus to use the new
ServerCallTracer interface. Note that the interfaces nor the code are in
their final states. There are a bunch of moving pieces, but I thought
this might be a nice mid-step to check-in and make sure that our
internal traces can also work with these changes.
Overall changes -
1) call_tracer.h shows what the hierarchy of new call tracer interfaces
looks like. Open to renaming suggestions.
2) Moved most of the common interface between `CallAttemptTracer` and
`ServerCallTracer` into a common `CallTracerInterface`. We should be
able to eventually move `RecordReceivedTrailingMetadata` and `RecordEnd`
as well to these common interfaces, but it requires some additional
work.
3) The compression filter is now responsible for recording the recv and
send messages for both the subchannel call and the server, and adds in
ability to record compressed and decompressed messages as well.
4) The OpenCensus server filter now uses the new `ServerCallTracer`
interface, and so doesn't need to be a filter anymore.
5) A new ServerCallTracerFilter was added. Ideally, we should be able to
move it to the current connected filter, but it is in a bit of an
interesting state right now, so I would prefer making those changes in a
separate PR with Craig's eyes on it.
6) A new context element `GRPC_CONTEXT_CALL_TRACER_ANNOTATION_INTERFACE`
was created that replaces the old `GRPC_CONTEXT_CALL_TRACER`, and the
new `GRPC_CONTEXT_CALL_TRACER` is mainly to pass the `CallAttemptTracer`
down the stack. This should go away in the new promise-based world.

* Revert "Revert "xDS RouteConfig: use ValidationErrors and add unit test (#31418)" (#31653)"
This reverts commit 335b74fea7.
* use auto instead of explicitly naming the protobuf map type
Specific changes:
- Use absl::variant<> for HashPolicy types.
- Pull validation of resulting LB policy configs out of ClusterSpecifierPlugin registry and into RouteConfig validation.
- Don't ignore missing Any fields in HTTP filter configs if is_optional is true, since is_optional should apply only to unsupported filter types, not to malformed resource protos.
- Use ExtractXdsExtension() for HttpConnectionManager config itself.
- Minor API improvements to StatusCodeSet to make it a bit more useful in tests.
- Changed StringMatcher to return the underlying error message when a regex fails to compile.
- Fix a bug whereby a ClusterSpecifierPlugin would not be returned if it was not used in a vhost, even if it was used in another vhost.
