[lldb][NFC] Replace const std::vector& with ArrayRef in APIs

Inside the LLVM codebase, const vector& should just be ArrayRef, as this
more general API works both with vectors, SmallVectors and
SmallVectorImpl, as well as with single elements.

This commit replaces two uses introduced in
llvm#168797 .
