[MLIR][IR] add -mlir-print-unique-ssa-ids to AsmPrinter (#91241)

Add an option to unique the numbers of values, block arguments and
naming conflicts when requested and/or printing generic op form. This is
helpful when debugging. For example, if you have:

    scf.for
      %0 =
      %1 = opA %0

    scf.for
      %0 =
      %1 = opB %0

And you get a verifier error which says opB's "operand #0 does not
dominate this use", it looks like %0 does dominate the use. This is not
intuitive. If these were numbered uniquely, it would look like:

    scf.for
      %0 =
      %1 = opA %0

    scf.for
      %2 =
      %3 = opB %0

And thus, much clearer as to why you are getting the error since %0 is
out of scope. Since generic op form should aim to give you the most
possible information, it seems like a good idea to use unique numbers in
this situation. Adding an option also gives those an option to use it
outside of generic op form.
