* replace darwin checks in extconf.rb to exclude TruffleRuby
* inherit RANLIB and STRIP from RbConfig, set LDXX
* enable overriding ranlib command in top-level makefile
* ensure the -no_warning_for_no_symbols flag is only used with Apple's ranlib
* don't embed openssl & zlib on truffleruby
* add RbConfig's cppflag to CPPFLAGS when using TruffleRuby
* this ensure the paths to find the system's OpenSSL are set up correctly with TruffleRuby (includes being able to find an OpenSSL installed via Homebrew etc)
* don't statically link standard libraries on Linux with Truffleruby
* This does not work when compiling to bitcode.
* Prefer SIGTERM to SIGQUIT for graceful shutdown in examples
* Overriding SIGQUIT is suboptimal, for example on JVM where it is very
useful to dump the thread stacktraces.
* Keep the rb_tr_abi_version symbol for TruffleRuby in grpc_c.so
* Otherwise TruffleRuby cannot verify the ABI version is correct.
* See https://github.com/oracle/truffleruby/issues/2386
* Use RbConfig::CONFIG['STRIP'] instead of just `strip`
* Use a local variable for apple_toolchain for consistency
* Add a comment about -static-libgcc -static-libstdc++ and TruffleRuby
* Split comment into two for openssl/zlib

* 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.

* Ran `2to3` on `tools/buildgen` and the `gen_build_yaml.py` files.
* Updated the invocations of python to be explicitly Python 3.
* Changed the loader in `mako_renderer.py` to allow pickle to find the module for pickling `external_version.Version`
* Added a few open-as-binary to placate readers/writers expecting bytes.
* Hand tweaked the templates to remove `iteritems` and fiddle with encodings.
Partially addresses #24359.
