Looks like our MSAN build is just taking longer at the moment, so increase sharding to reduce per-shard runtime.

In some rare occasions on Win machines (0,2-0,5%), the tests are stuck before the handshake when we execute `grpc_call_start_batch`. We receive OP_COMPLETE with `Deadline Exceeded {grpc_status:4}` for such cases. The PR bumps it from 5 to 30s (no flakes for --runs_per_test=1000).

MetadataPluginCallCredentials passes a function pointer to C-core to be called during destruction. This function grabs GIL which may race between GIL destruction during process shutdown. Since GIL destruction happens after Python's exit handlers, we cana mark that Python is shutting down from an exit handler and don't grab GIL in this function afterwards using a C mutex.

Previously, if we pulled server trailing metadata *before* the call was added to the client transport then we'd never call `on_done_` on the spine and consequently never remove the call from the map. This change fixes that edge case.
In fixing it, I noticed a state in `CallState` that was both complicating the fix and completely irrelevant because we respecced earlier this year to say that ServerTrailingMetadata processing cannot be asynchronous, so I'm removing that state also.

The gRPC Core API currently requires callers to provide initial metadata before trailing metadata. You can see the C++ Callback API do this bookkeeping, for example. There is an eventual goal to be able to provide these in any order, and have gRPC do the right thing, but core is not there yet.
The proxy fixture in our end2end tests had a rare scenario in which trailing metadata from the server would show up at the proxy before initial metadata. This is part of the proxy's job: to split up batches into singular-operations that can complete in any order. There was, however, a rare flake wherein trailing metadata would complete before initial metadata, and the result was both client and server waiting on each other to respond.
This change adds a way for the proxy to defer sending trailing metadata back to the client, until after initial metadata has been sent to the client. In my testing, this eliminates the flake I had been able to reproduce 1 in 10k times using a single test. It happened more frequently across the full set of tests in our CI test suites.

It's possible for `LogStateChange` to be called after the party is destroyed (one thread calls Unref, which calls LogStateChange after the atomic op; another calls Unref concurrently, frees the last ref, deletes the object)
Consequently, it's not safe to call `DebugTag()` here - remove that.

This PR does two things:
1. Increase timeout for test case from `480s` to `600s`.
2. Add timestamp to test starting and passing so we know which test case takes a long time to run.

In the logs, looks like we're creating gen2 functions by default:
```
As of this Cloud SDK release, new functions will be deployed as 2nd gen functions by default. This is equivalent to currently deploying new with the --gen2 flag. Existing 1st gen functions will not be impacted and will continue to deploy as 1st gen functions.
```
Since we don't need functions provided by gen2 functions and use `--no-gen2` fixed the permission issue, we're adding `--no-gen2` flag to our test.

Pretty sure that the `LoadBalancedCall` instance is getting dropped before return on *some* path through `PickSubchannel`, although it's unclear to me which and it's hard to tell with this implementation.
Ensure that such an event cannot cause a crash by holding a ref to the object we need and calling through that.
This will be marginally worse performance per pick for now, but once work serializer dispatch lands everywhere the additional ref will disappear.
