Disable on Server Core 3 tests that use Notepad

[danmoseley]

Fixes #26231
Fixes #44239

Since a207c7f 3 Process tests still fail consistently, and only on Server Core:

StartInfo_TextFile_ShellExecute

This means ShellExecuteExW succeeded, but even though we passed SEE_MASK_NOCLOSEPROCESS it did not fill in the hProcess. The docs say

Even if fMask is set to SEE_MASK_NOCLOSEPROCESS, hProcess will be NULL if no process was launched. For example, if a document to be launched is a URL and an instance of Internet Explorer is already running, it will display the document. No new process is launched, and hProcess will be NULL.

Yet it does launch notepad. Although the failure is consistent I am not able to repro locally on a Server Core container, ie the following works

PS C:\Users\danmose> $psi = new-object System.Diagnostics.ProcessStartInfo
PS C:\Users\danmose> $psi.UseShellExecute = $true
PS C:\Users\danmose> dir >c:\temp\foo.txt
PS C:\Users\danmose> $psi.FileName = "c:\temp\foo.txt"
PS C:\Users\danmose> $ps = [System.Diagnostics.Process]::Start($psi)
PS C:\Users\danmose> $ps -eq $null
False

So I am just disabling this test for Server Core.

StartInfo_NotepadWithContent_withArgumentList
StartInfo_NotepadWithContent

I tried both notepad and regedit on Server Core -- the process launches, but GetWindowText always returns blank. So, disabling checking the title on Server Core.

LGTM. Should we be closing the linked issues?

[danmoseley]

I closed them as realistically I don't think there is further action we are going to take and I think that's OK. We are still testing shellexec on this OS.
