Feature Request: Add MsBuildArgument supports for MSBuild special characters

[filzrev]

Currently MsBuildArgument constructor accept single string argument.
And this string value is passed to MSBuild command line parameter as is.

So when specified string contains MSBuild special characters
It needs manually escape these characters.
(e.g. When passing list values. It need to escape semicolon(;) char to %3B)

Is it able to handle these special characters inside MsBuildArgument class?
or add [MsBuildArgument constructor] that accept string params to handle multiple values?

Test Code

    internal class Program
    {
        static void Main(string[] args)
        {
            BenchmarkRunner.Run<Benchmarks>();
        }
    }

    [Config(typeof(CustomConfig))]
    public class Benchmarks
    {
        [Benchmark]
        public void Benchmark01()
        {
#if TEST1 && TEST2
            // DefineConstants symbols are defined as expected.
#else
            throw new Exception("DefineConstants value is unexpected value!");
#endif
        }

        public class CustomConfig : ManualConfig
        {
            public CustomConfig()
            {
                AddLogger(ConsoleLogger.Default);

                AddColumnProvider(DefaultConfig.Instance.GetColumnProviders().ToArray());
              
                AddJob(Job.ShortRun
                    .WithStrategy(RunStrategy.Monitoring)
                    .WithArguments(
                    [
                       // new MsBuildArgument("/p:DefineConstants=TEST1;TEST2"),     // Error: MSBUILD : error MSB1006: Property is not valid.
                       // new MsBuildArgument("/p:DefineConstants=\"TEST1;TEST2\""), // Double quote does not works.
                       new MsBuildArgument("/p:DefineConstants=TEST1%3BTEST2"),      // It works when using MSBuild special character
                    ])
                    .WithId("CustomJob"));

                WithOption(ConfigOptions.KeepBenchmarkFiles, true); // Use this settings for output to JobId folder
            }
        }
    }

I think it's reasonable to escape those characters in the MsBuildArgument ctor.

Double quote does not works.

It seems double quote is stripped on .bat execution timing.
So, it need to escape " char also on Windows environment.
(e.g. new MsBuildArgument("/p:DefineConstants=\\\"TEST1;TEST2\\\""))

I'll try to create PR later to resolve this issue.
