[build] Target net7.0 (#988)

Context: dotnet/android#6598
Context: dotnet/android#7028

Update `$(TargetFrameworks)` across the various `.csproj` files to
use `$(DotNetTargetFramework)`, as xamarin/xamarin-android does.
Additionally, set `$(DotNetTargetFramework)`=net7.0 (.NET 7).

Similar to commit e7bacc3, Mono cannot be used to build against
.NET 7 reference assemblies:

	/Library/Frameworks/Mono.framework/Versions/6.12.0/lib/mono/msbuild/Current/bin/Microsoft.Common.CurrentVersion.targets(1232,5):
	error MSB3971: The reference assemblies for ".NETFramework,Version=v7.0" were not found.
	You might be using an older .NET SDK to target .NET 5.0 or higher.
	Update Visual Studio and/or your .NET SDK.

Fix this by updating the **Mac - Mono** CI job to *build* with .NET 7,
while Mono-focused unit tests are still run with Mono.

Note: dotnet/android#7028 will be required in order to bump
Java.Interop within xamarin-android.
