Update to Content Builder .targets to work for any build configuration (

#9176)

# Summary

Templates update to enable the Content Builder `.targets` file to work
for any build configuration.

- `Content.csproj` updated to not use the "target framework" in build
output to simplify launching
- `Builder.targets` updated to decouple itself from the host platforms
"configuration" and fixed to run as "Debug" when attached to a solution

`content.csproj` update:
```xml
<AppendTargetFrameworkToOutputPath>false</AppendTargetFrameworkToOutputPath>
```

`builder.targets` update:
```xml
<Project>
  <Target Name="BuildContent" BeforeTargets="BeforeCompile">
    <PropertyGroup>
      <ContentOutput>$(ProjectDir)$(OutputPath)</ContentOutput>
      <ContentTemp>$(ProjectDir)$(IntermediateOutputPath)</ContentTemp>
      <ContentArgs>build -p $(MonoGamePlatform) -s Content/Assets -o $(ContentOutput) -i $(ContentTemp)</ContentArgs>
      <ContentCommand>$(MSBuildThisFileDirectory)bin\Debug\Content</ContentCommand>
    </PropertyGroup>
    <MSBuild Projects="$(MSBuildThisFileDirectory)Content.csproj" Targets="Build" RemoveProperties="Configuration;TargetFramework;RuntimeIdentifier;RuntimeIdentifiers" />
    <Exec Command="$(ContentCommand) $(ContentArgs)" WorkingDirectory="$(MSBuildThisFileDirectory)..\" CustomErrorRegularExpression="\[E\] .+" CustomWarningRegularExpression="\[W\] .+" />
   </Target>
</Project>
```

Minor patch fix to CB StartKit to ignore `ttf` files to supress warning
that `ttf` file could not be processed (which is correct, it is consumed

Update Copyright to MonoGame Foundation, Inc (#9150)

More Fixes going all the way back to
#[8101](#8101)

### Description of Change

Updates remaining Headers with the previous **The MonoGame Team**
copyright to match the new Foundation Copyright standard. I happened to
be playing around with the newer native implementations and noticed the
CType generators had the older copyright text and then I went down this
rabbit hole of finding more and more.

I apologize for the big PR! It really is just comment updates with the
exception of these files that have impactful changes to the comments
created on newly generated CTypes files:

Tools/MonoGame.Generator.CTypes/EnumWritter.cs
Tools/MonoGame.Generator.CTypes/PInvokeWritter.cs
Tools/MonoGame.Generator.CTypes/StructWritter.cs
