Improve Bazel build files.
New target gtest_prod allows access to the FRIEND_TEST macro without depending on the entirety of GTest in production executables. Additionally, duplicate config_setting rules were removed and formatting was adjusted.

This change adds the ability to generate stacktraces in Google Test on
both failures of assertions/expectations and on crashes. The
stacktrace support is conditionally available only when using Abseil
with Google Test.
To use this support, run the test under Bazel with a command like this:
bazel test --define absl=1 --test_env=GTEST_INSTALL_FAILURE_SIGNAL_HANDLER=1 //path/to/your:test
The "--define absl=1" part enables stacktraces on assertion/expectation
failures.
The "--test_env=GTEST_INSTALL_FAILURE_SIGNAL_HANDLER=1" part enables
the signal handler that logs a stacktrace in the event of a crash
(this also requires the "--define absl=1" part). This is not the
default since it may interfere with existing tests.
