[dotnet] allow user to start service before creating driver

[titusfortner]

Description

Create a GetDefaultDriverOptions() method in each driver service class to allow passing to the DriverFinder method if starting the driver without a provided location.

Motivation and Context

Fixes #12805
Similar to how 5bce8d9 fixes #12682

@titusfortner I don't believe this issue has been addressed entirely. I'm running into the same error message as documented in #12805 using the latest version of Selenium (4.14.1).

While debugging through the code, I see that this call to DriverFinder.FullPath(GetDefaultDriverOptions()); (line 221) isn't setting the private members driverServicePath and driverServiceExecutableName, which I believe in turn causes the call to driverServiceProcess.StartInfo.FileName = Path.Combine(driverServicePath, driverServiceExecutableName); in DriverService.cs to fail at line 224.

I have reopened that issue, thanks for the report.
