Fix a few netci issues

1. Computing GC roots is a relatively slow operation, and doing it for every state machine object found in a large heap can be time consuming.  Making it opt-in with -roots command-line flag.

2. Added -waiting command-line flag.  DumpAsync will now retrieve the <>1__state field from the StateMachine, and if -waiting is specified, it'll filter down to state machines that have a state value >= 0, meaning the state machines are waiting at an await point.  For example, given this program:
```C#
using System.Threading.Tasks;
class Program
{
    static async Task Main() { await MethodA(0); await MethodA(int.MaxValue); }
    static async Task MethodA(int delay) => await MethodB(delay);
    static async Task MethodB(int delay) { await Task.Yield(); await Task.Delay(delay); }
}
```
using `!DumpAsync` outputs:

skipping the two state machines that have a `<>1__state` field value of -2 (meaning it's completed).  Note that this change has the somewhat unfortunate impact of taking a dependency on what's effectively an implementation detail of Roslyn, but the value the filtering provides is deemed to be worth it.  This design is unlikely to change in the future, and as with other diagnostic/debugging features that rely on such details, it can be updated if Roslyn ever changes its scheme.  In the meantime, the code will output a warning message if it can't find the state field.

3. If a state machine is found to have 0 roots but also to have a <>1__state value >= 0, that suggests it was dropped without having been completed, which is likely a sign of an application bug.  The command now prints out an information message to highlight that state.  For example, this program:
```C#
using System;
using System.Threading.Tasks;
class Program
{
    static void Main()
    {
        Task.Run(async () => await new TaskCompletionSource<bool>().Task);
        Console.ReadLine();
    }
}
```
when processed with `!DumpAsync -roots` results in:

This change contains the remaining fixes I made while digging
through the PR run in the runtime repo:

1) Some more repo-relative vs. coreclr-relative repo adjustments
reflecting the migration process;

2) Make sure that XunitTestBinBase always ends with a directory
separator, otherwise my recent fix for Common folder exclusion
doesn't work;

3) Opportunistically shorten project names of two native interop
test components - as the project name is repeated about 3-4 times
in some intermediate paths, it quickly exceeds the standard
Windows path length limit. Please note there's no functional
change in the test.

Thanks
