[Bazel] Add more llvm tools (#163228)

Adding llvm-ir2vec, llvm-ctxprof-util (and llvm-sim) in the Bazel
configs. llvm-ctxprof-util and llvm-ir2vec are used in several LIT unit
tests, and the missing binary is causing unit test failures.

llvm-ctxprof-util:
https://github.com/llvm/llvm-project/blob/15cde999d47c3edc7647faf5fd967f5d5d88416a/llvm/test/Analysis/CtxProfAnalysis/flatten-icp.ll#L2

llvm-ir2vec:
https://github.com/llvm/llvm-project/blob/55d4e92c8821d5543469118a76fe38db866377b7/llvm/utils/mlgo-utils/IR2Vec/generateTriplets.py#L60

llvm-sim:
https://github.com/llvm/llvm-project/blob/894eaf481542adefde861a7e39f769f21d3f4fa4/llvm/test/lit.cfg.py#L268
