  -----------
  [clang][Syntax] syntax::Arena doesnt own TokenBuffer

Currently an Arena can only be built while consuming a TokenBuffer,
some users (like clangd) might want to share a TokenBuffer with multiple
compenents. This patch changes Arena's TokenBuffer member to be a reference so
that it can be created with read-only token buffers.
