[Bug 45333] Add diagnostic 'mscoree.dll.CorGetSvc' stub to hint at broken Microsoft .NET Frameworks installation ( Wine-Mono not uninstalled and 'mscoree.dll' placeholders not removed prior install)

Hello Louis,

it seems the cause of crash is stack imbalance.
I added a FIXME stub without message box:

wine: Call from 0x7b446fe6 to unimplemented function mscoree.dll.CorGetSvc,
aborting
--- snip ---

'mscoree.CorIsLatestSvc()' is called on the NGEN service process side and
causes an exception on return due to stack being 8 bytes off -> 2 integer args
= return address 0. It gets caught within a SEH, letting the service not to
crash. The NGEN service will exit with following message though:

--- snip ---
0019:err:eventlog:ReportEventW L".NET Runtime Optimization Service
(clr_optimization_v4.0.30319_32) - Tried to start a service that wasn't the
latest version of CLR Optimization service. Will shutdown\n"
--- snip ---

This will not be seen by most users as they don't start apps from terminal and
most don't pay attention at all to such kind of messages.

The client side 'ngen.exe' calls unimplemented 'mscoree.dll.CorGetSvc'.
That one is actually documented:

https://github.com/dotnet/coreclr/blob/master/src/inc/mscorsvc.idl#L21

--- snip ---
#pragma midl_echo("STDAPI CorGetSvc(IUnknown **pIUnknown);")
--- snip ---

--- snip ---

I'm not sure if it's really wise to put a message box to an API which is called
from within a service process. It might be better to add the message box to
'mscoree.dll.CorGetSvc()' which is called by the client side.

--- snip ---

The NGEN client will change the 32-bit and 64-bit NGEN service start type to
'manual start' after encountering this problem once.
The service(s) will not be started any more by design.
