Fix some flakiness caused by fixing jitter in the backoff library in #37595.
In the xDS retry tests, the additional jitter made it such that an extra attempt snuck in before the call deadline, so I adjusted the knobs to ensure that exactly the expected number of attempts fit into the tests.
In the PF test, I rewrote the test to use a connection injector, so that it can more accurately tell the time between the connection attempts, without seeing skew due to the server startup time.

Final piece of gRFC A83 (https://github.com/grpc/proposal/pull/438): the GCP authentication filter itself.
Infrastructure changes include:
- Added a general-purpose LRU cache library that can be reused elsewhere.
- Fixed the client channel code to use the channel args returned by the resolver for the dynamic filters. This was necessary so that the GCP auth filter could access the `XdsConfig` object, which is passed via a channel arg.
- Unlike the other xDS HTTP filters we support, the GCP auth filter does not support config overrides, and its configuration includes a cache size parameter that we always need at the channel level, not per-call. As a result, I had to change the xDS HTTP filter API to give it the ability to set top-level fields in the service config, not just per-method fields. (We use the service config as a way of passing configuration down into xDS HTTP filters.) Note that for now, this works only on the client side, because we don't have machinery for a top-level service config on the server side.
- The GCP auth filter is also the first case where the filter needs to know its instance name from the xDS config, so I changed the xDS HTTP filter API to plumb that through.
- Fixed a bug in the HTTP client library that prevented the override functions from declining to override a particular request.

[Gpr_To_Absl_Logging] Remove gpr logging header include from other headers
Some of the cc files are using gpr_log_verbosity_init() functions.
So I removed the #include <grpc/support/log.h> from all headers and put it selectively only in the cc files that used gpr_log_verbosity_init()

As per gRFC A81 (https://github.com/grpc/proposal/pull/435).
A few small improvements along the way:
- Use `DownCast<>` instead of `static_cast<>` in `ServiceConfigCallData::GetCallAttribute()`.
- Add a convenient templated wrapper for `ClientChannelLbCallState::GetCallAttribute()`, similar to the one on `ServiceConfigCallData`.
- Added a `ParseBoolValue()` helper to xds_common_types_parser, and use it in various places in xDS resource parsing.

PiperOrigin-RevId: 650293912
As part of the xDS authority rewriting implementation in #37087, I need to write some tests showing the authority being rewritten. However, the fake security connector currently crashes on unexpected authorities. (As a side note, I think the fake security connector is very cumbersome and should be redesigned, but that's a separate project.) As a result, I need a way to use InsecureCreds on a per-test basis.
I thought about just adding an option to `XdsTestType` to trigger use of InsecureCreds, but the logic we use for determining which creds type to use for what is already very cumbersome, and adding another option there would have just made that worse. Instead, I have switched to a simpler approach where the individual tests can decide what creds type to use directly. This both unblocks my other PR and makes the existing code more maintainable.

This fixes a fairly embarrassing bug and lack of testing from #33234. Prior to this fix, attempting to use the "tls" creds type would always cause a crash.
@gtcooke94@matthewstevenson88 Note that the root cause of this bug was that when I wrote this code, I assumed that `grpc_tls_credentials_options` had a reasonable default for the cert verifier. But it turns out that it doesn't do that directly; instead, we are only imposing that default in [`CredentialOptionSanityCheck()`](621aa4e5ce/src/core/lib/security/credentials/tls/tls_credentials.cc (L85)), which is called only when we call [`grpc_tls_credentials_create()`](621aa4e5ce/src/core/lib/security/credentials/tls/tls_credentials.cc (L160)), not when we directly instantiate `TlsCredentials` as my code was doing. As part of the TlsCreds API cleanup you're working on, we should fix this so that callers get the right behavior even if they are internal callers that instantiate the TlsCreds object directly rather than calling the C-core API.

[grpc][Gpr_To_Absl_Logging] Migrating from gpr to absl logging - gpr_log
In this CL we are migrating from gRPCs own gpr logging mechanism to absl logging mechanism. The intention is to deprecate gpr_log in the future.
We have the following mapping
1. gpr_log(GPR_INFO,...) -> LOG(INFO)
2. gpr_log(GPR_ERROR,...) -> LOG(ERROR)
3. gpr_log(GPR_DEBUG,...) -> VLOG(2)
Reviewers need to check :
1. If the above mapping is correct.
2. The content of the log is as before.
gpr_log format strings did not use string_view or std::string . absl LOG accepts these. So there will be some elimination of string_view and std::string related conversions. This is expected.

Replacing GPR_ASSERT with absl CHECK
These changes have been made using string replacement and regex.
Will not be replacing all instances of CHECK with CHECK_EQ , CHECK_NE etc because there are too many callsites. Only ones which are doable using very simple regex with least chance of failure will be replaced.
Given that we have 5000+ instances of GPR_ASSERT to edit, Doing it manually is too much work for both the author and reviewer.

Forked from #35957
This PR refactors the credentials types to remove Secure and Insecure Channel and Call credentials types. We standardize on a `c_creds()` accessor method for all credentials types, which can now be treated uniformly. This notably removes special-case handling of insecure credentials.
The special code-paths for insecure creds are no longer necessary in the wake of #25586.
