* [chttp2] Tune initial window size/max frame size setting
- Only choose frame sizes and initial window sizes that are powers of two - as a more predictable function to avoid flapping.
- If window size drops below 1kb then snap to 0 to avoid frantically changing a value that needn't be
- Allow the initial window size to drop to zero (we have fuzzing in place that says this is safe)

* [arena] Add ManagedNew(), gtest-ify test
Add a ManagedNew() method to Arena that calls the relevant destructor at Arena destruction time.
There are some cases coming up in the promise based call work where this becomes super convenient, and I expect it's likely that there are other places that's true too.

* first pass at excluding EventEngine test expansion
Also caught a few cases where we should not test pollers, but should
test all engines. And two cases where we likely shouldn't be testing
either product.
* end2end fuzzers to be fuzzed differently via EventEngine.

* Tooling to remove redundant grpc_core:: namespaces
These references tend to show up in our C++ code after C modules get
converted. Many get caught in review, many get missed.

* Expand Table, BitSet API's
Add a population count to BitSet, use it to add a count() method to
Table to get the number of fields set.
Add a ForEach to Table so that it can be iterated

* Generalize pthread TLS to any trivial type
Use multiple pthread keys for types larger than a machine word.
Implement generic timer TLS optimization on all platforms.
See code commentary for an explanation.
Add an additional constructor to allow `log_linux.cc` to compile with
GPR_PTHREAD_TLS. Without it:
```
../../third_party/grpc/src/core/lib/gpr/log_linux.cc:78:33: error: no viable conversion from 'int' to 'grpc_core::PthreadTlsImpl<long>'
static GPR_THREAD_LOCAL(long) tid = 0;
^ ~
../../third_party/grpc/src/core/lib/gpr/tls.h:64:3: note: candidate constructor not viable: no known conversion from 'int' to 'const grpc_core::PthreadTlsImpl<long> &' for 1st argument
PthreadTlsImpl(const PthreadTlsImpl&) = delete;
^
1 error generated.
```
* Implement type safety for TLS
This is mostly free when compiler support is available, but requires
careful templating when implemented using pthread.
Significantly slimmed the tls.h interface; it now only defines the "TLS
keyword" for each supported compiler, delegating enforcement of correct
usage (i.e. must be static) to the compiler itself.
Implemented implicit conversion for the pthread wrapper so it can be
used (mostly) the same as native support. Notable exception to this is
that static_cast<void*> is needed when printing a pointer stored in TLS
as %p.
* Use GPR_THREAD_LOCAL macros consistently
