I think we stopped using `__find_end` since 101d1e9b3c867b2fbb9d1b2c196e2f0fcf3467c7 (https://reviews.llvm.org/D124079) when implementing `ranges::find_end`.

@hewillk Could you add this to the the PR description, and make the title clearer, e.g. by saying "[libc++][NFC] Removed no longer used internal helper `__find_end`"?
