This will disable the jobs in both bazel and cmake builds, which is necessary for our CI to remain happy. These end2end tests were enabled on Windows at some point without any notice (they had been intentionally disabled for a while), but the RBE jobs have been silently failing for 7 months, so it's unclear when that happened.
These failures still need to be examined so we can re-enable these tests.

Porting from #37829.
This ensures that we wait to create the stream to the handshaker service until handshake frames arrive from the client. Without this change, a TCP connection to the ALTS server triggers the stream to the handshaker service to be created, even if no handshake frames have arrived from the client. This waste resources and can potentially trigger the ALTS server to freeze up, because there is a cap on the number of concurrent ALTS handshakes that a server can perform.

Don't complete writes of messages until they make it to the transports outbound loop. Since payloads could be large this introduces just enough pushback that, once #37868 goes in also we should be able to sense when a transport is busy writing and stop sending at higher layers.

- in v2 we had Pipe setup so that multiple Pipe stages could be chained and only complete when the last stage had passed flow control, whereas in v3 the top stage will start accepting requests as soon as the first stage in the pipeline takes the message.

To prepare for the upcoming upgrade to C++17, the following changes were made:
Increased minimum supported operating system versions:
- iOS: 11 (previously 10)
- macOS: 10.14 (previously 10.12)
- tvOS: 13.0 (previously 12.0)
In addition to this, version requirements across different projects were updated to use these for consistency.

So far missing for HTTP/2 style flow control has been a primitive to query whether there's a receiver for flow control data at the other end of the message pipes.
Here I'm updating the state machine accessors to accommodate that functionality.
No new states were needed.
Whilst here, document the current member functions on `CallState`.

Fix https://github.com/grpc/grpc/issues/37727.
A better idea might be to set up Fuzzing for these APIs to find those sort of things. Maybe that can be a next step if we want to further hardening things.

Add a ValidateCredentials API to the TLS certificate provider interface. A user can call this API to check that the credentials currently held by the certificate provider instance are valid. The definition of "valid" depends on provider that is being used. For the static data and file watcher providers, "valid" means that the credentials consist of valid PEM.
~Currently there is no check to ensure that credentials consist of valid PEM blocks before a TLS handshake commences. This PR creates a static factory for FileWatcherCertificateProvider (and marks the constructor as deprecated) which performs this validation check. The analogous work for StaticDataCertificateProvider will be done in a follow-up PR.~

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.

This change adds an experiment to move time caching from `ExecCtx` (which is the wrong place for this mechanism) and moves it to the party update path (the expectation being that a single poll of a call is the granularity at which we expect time caching to be a useful optimization, whilst avoiding the unbounded hold times associated with the current mechanism).
This requires fixing up a few tests that grew to depend on time caching (would appreciate close eyes on the credentials test, as it's unclear to me why this is required or what the effect is).
This should also fix b/232544809.
