Remove clang-rename (#108988)

clang-rename has largely been superseded by clangd and this project
hasn't received much attention in many years. Further, our
documentation on it still claims it's in very early stages of
development despite being ~10 years old. One of the primary people
driving the tool has mentioned that they don't believe there is a
reason to continue to support it unless it's still being actively
used (https://reviews.llvm.org/D148439#4303202) and I've found no
evidence to suggest that is the case.
