Cleanup stacktrace_config.h

Instead of listing the platforms that aren't supported, list the ones
we do support, and fallback to stacktrace_unimplemented-inl.inc at the
end. Previously any platform that wasn't listed gets "#error Not supported yet".

GitHub issue #135

Make the absl::SleepFor() tests treat any successful retry within
a 48x deadline as a total success, thereby reducing flakiness.

Replace config_setting.values{"compiler"} with config_setting.flag_values{"@bazel_tools//tools/cpp:compiler"}

Due to changes in Bazel we need to change the way "compiler" is specified in config_setting. This will not change the behavior of the config_setting itself.

Address test flakiness in the TimeoutTest.

The basic idea is to loop forever until the expected
scheduling delays are observed (within reasonable bounds),
and only then assert the other invariants.
