perf probe: Introduce quotation marks support

In non-C languages, it is possible to have ':' in the function names.

It is possible to escape it with backslashes, but if there are too many
backslashes, it is annoying.

This introduce quotation marks (`"` or `'`) support.

For example, without quotes, we have to pass it as below

  $ perf probe -x cro3 -L "cro3\:\:cmd\:\:servo\:\:run_show"
  <run_show@/work/cro3/src/cmd/servo.rs:0>
        0  fn run_show(args: &ArgsShow) -> Result<()> {
        1      let list = ServoList::discover()?;
        2      let s = list.find_by_serial(&args.servo)?;
        3      if args.json {
        4          println!("{s}");

With quotes, we can more naturally write the function name as below;

  $ perf probe -x cro3 -L \"cro3::cmd::servo::run_show\"
  <run_show@/work/cro3/src/cmd/servo.rs:0>
        0  fn run_show(args: &ArgsShow) -> Result<()> {
        1      let list = ServoList::discover()?;
        2      let s = list.find_by_serial(&args.servo)?;
        3      if args.json {
        4          println!("{s}");
