[ItaniumDemangle] Add customizable printLeft/printRight APIs to OutputBuffer (#133249 )

This patch includes the necessary changes for the LLDB feature proposed
in
https://discourse.llvm.org/t/rfc-lldb-highlighting-function-names-in-lldb-backtraces/85309.
The TL;DR is that we want to track where certain parts of a demangled
name begin/end so we can highlight them in backtraces.

We introduce a new `printLeft`/`printRight` API on `OutputBuffer` that a
client (in our case LLDB) can implement to track state while printing
the demangle tree. This requires redirecting all calls to to
`printLeft`/`printRight` to the `OutputBuffer`. One quirk with the new
API is that `Utility.h` would now depend on `ItaniumDemangle.h` and
vice-versa. To keep these files header-only I made the definitions
`inline` and implement the new APIs in `ItaniumDemangle.h` (so the
definition of `Node` is available to them).

Also introduces `notifyInsertion`/`notifyDeletion` APIs that a client can override to respond to cases where the `OutputBuffer` changes arbitrary parts of the name.
