* Drop ABSL_RANDOM_HWAES_FLAGS compiler flags
Older CPUs that do not have SSE4.1 would crash with the Ruby native gem
due to an illegal instruction exception.
The Abseil random library isn't being used at the moment
(https://github.com/grpc/grpc/pull/26476), and there's no reason gRPC
needs to force SSE4.1 instructions on all platforms at the moment. There
are other hardware-specific issues that need to be ironed out for this
to work: https://github.com/grpc/grpc/pull/26479
When the `-msse4` compiler flag was enabled, the Abseil code started
using the `pinsrb` instruction:
```
$ elfx86exts abseil-cpp/absl/time/internal/cctz/src/time_zone_libc.o
MODE64 (ret)
CMOV (cmovne)
SSE2 (movdqa)
SSE41 (pinsrb)
SSE1 (movaps)
CPU Generation: Penryn
```

This was previously needed because gcc 4.8 wouldn't compile without the
`-msse4` and `-maes` flags.
However, per
97db2bf7fb
gcc 5.0+ automatically detects whether these options are enabled.
clang still needs `-maes` since including `wmmintrin.h` expects the AES
option to be enabled.

A reusable test suite for EventEngine implementations.
To exercise a custom EventEngine, simply link against :event_engine_test_suite
and provide a testing main function that sets a custom EventEngine factory:
```
#include "path/to/my_custom_event_engine.h"
#include "src/core/event_engine/test_suite/event_engine_test.h"
int main(int argc, char** argv) {
::testing::InitGoogleTest(&argc, argv);
SetEventEngineFactory(
[]() { return absl::make_unique<MyCustomEventEngine>(); });
auto result = RUN_ALL_TESTS();
return result;
}
```
It used to be that we could run the hpack deserializer into an arbitrary
sink - that's about to change and the hpack deserializer will buffer
directly into a map. That being the case, it's really hard to compare
performance of the current and the new system. With this PR, I'm
updating the relevant scenario to be more similar to the eventual
scenario that we plan, so that as the new work finishes up, we can get a
clearer idea of what changes we're really making.
