toolchain-utils: Remove buildbot_test_llvm.py

As far as I can tell, this file is no longer used by anything internally
or externally. The program doesn't seem to work either, and hasn't had
a functional update since 2019.

It uses command_executor, and we're trying to clean up uses
of that wherever possible.

BUG=b:289058911
TEST=./run_tests_for.py cros_utils/*test*
