* Correctly fetch the IVsBuildMacroInfo to use for the build events page

This code is blindly copied and pasted from https://github.com/dotnet/project-system/blob/88606ba869a29aa24979e0d14a199b2430f31f43/src/Microsoft.VisualStudio.Editors/PropPages/BuildEventsPropPage.vb#L162-L176
I will fully admit I have no idea how this is supposed to work.

* Even more correctly fetch the IVsBuildMacroInfo to use for the build events page

My previous change broke projects with the old project system. Try
the old path and if that doesn't work, then try the new path.

The signed build can't consume C# pattern matches.  Also rename the file to match the class name.

* add another test for #3254, ported from paket. related to #3350 and https://github.com/fsprojects/Paket/pull/2553

* Fix exception message

* Make F# resources work more like C#

Given a resource in a folder named `AFolder/AResourceFile.txt` in a project with
a root namespace of `fsharpresources`, then the following command line arg
should be passed to the compiler

```
--resource:AFolder/AResourceFile.txt,fsharpresources.AFolder.AResourceFile.txt
```

whereas currently it just passes the name of the file. This also fixes passing
a `LogicalName` to the resource.

I looked at how Roslyn was doing this [here](https://github.com/dotnet/roslyn/blob/6847f1e5a909395aae9456e8f366cbf4deb86b69/src/Compilers/Core/MSBuildTask/ManagedCompiler.cs#L739)

* Add a UseStandardResourceNames flag (disabled by default)

With
```
    <UseStandardResourceNames>true</UseStandardResourceNames>
```
we get the following output

```
--resource:AFolder/AResourceFile.txt,fsharpresource.AFolder.AResourceFile.txt
```

With the value omitted or set to false, the behaviour is as it was previously.

```
--resource:AFolder/AResourceFile.txt
```
