* xds-k8s jobs: standardize TESTING_VERSION (#30027) (#30048)

This Addresses the issue with skips not working in golang tests, ref b/235688697. 

1. Unifies `TESTING_VERSION` detection  in grpc_xds_k8s_install_test_driver.sh - new approach applicable to all languages.
2. Use `TESTING_VERSION` in all build files in `--testing_version` and when tagging docker images. This will be backported to all active test branches. Build Scripts in all other languages will be updated as well.

* 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.

* Fix leak on ares resolver test

The pollset was not being properly shutdown. ASAN was failing 100% on
resolve_address_using_ares_resolver_test for a month (not identified in
CI).

* DoNothgin -> nullptr

A minor refactoring.

Added a couple of tests which run the baseline_test with all released
bootstrap generator versions on client and server. These tests will be
run on a continuous integration environment with gRPC servers and
clients built using the latest released version of gRPC in one selected
language.

* Add supported Node version ranges in xDS k8s url_map tests

This adds is_supported implementations for most of the url_map tests that didn't
already have them. The exception is metadata_filter_test because it doesn't use
any specific client features.

* Fix formatting

* Improve timeout test check order

* BinderTransport: Fix wire reader/writer issue with NDK

NDK sometimes call registered `AIBinder_Class_onTransact`
callback while we call its `AIBinder_transact`.

Sometimes this behavior happens consistently sometimes it
don't happen at all. Likely related to the short circuit
behavior happens when both gRPC server and gRPC client are in the same
process.

This commit also fixes some other existing issue in wire writer.
