[One .NET] Fix targeting API 33, build API 31 ref pack (#6896)

Fixes: #6914 The Microsoft.Android `@(KnownFrameworkReference)` will now declare targeting and runtime pack metadata that is based on the `$(TargetPlatformVersion)` of the project file. The only exception to this rule is when '$(TargetPlatformVersion)' == '31.0'; in this case the project will use an API 31 ref pack with API 32 runtime packs. The inline `Microsoft.Android.Sdk.BundledVersions.targets` file content has been moved into a separate file to improve the readability of the `@(KnownFrameworkReference)` element. Breakdown of supported `$(TargetFramework)` -> ref/runtime pack used: | `$(TargetFramework)` | Targeting Pack | Runtime Pack | | -------------------- | -------------- | ------------ | | net6.0-android | Microsoft.Android.Ref.31 | Microsoft.Android.Runtime.32 | | net6.0-android31.0 | Microsoft.Android.Ref.31 | Microsoft.Android.Runtime.32 | | net6.0-android32.0 | Microsoft.Android.Ref.32 | Microsoft.Android.Runtime.32 | | net6.0-android33.0 | Microsoft.Android.Ref.33 | Microsoft.Android.Runtime.33 | Tests have been updated accordingly, and they will now use a dynamic test case source that should make sure we don't miss any coverage when making future updates to `$(AndroidDefaultTargetDotnetApiLevel)`, `$(AndroidLatestStableApiLevel)`, and `$(AndroidLatestUnstableApiLevel)`. If an unsupported `$(TargetFramework)` is used in a project file the following errors will now be displayed: "test.csproj" (_GenerateRestoreGraphProjectEntry target) (1:5) -> (ProcessFrameworkReferences target) -> C:\Program Files\dotnet\sdk\6.0.300-preview.22211.2\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.FrameworkReferenceResolution.targets(90,5): error : NETSDKZZZZ: Error getting pack version: Pack 'Microsoft.Android.Ref.25' was not present in workload manifests.

C:\Program Files\dotnet\sdk\6.0.300-preview.22211.2\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.FrameworkReferenceResolution.targets(90,5): error : NETSDKZZZZ: Error getting pack version: Pack 'Microsoft.Android.Runtime.25.android-x86' was not present in workload manifests. C:\Program Files\dotnet\sdk\6.0.300-preview.22211.2\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.FrameworkReferenceResolution.targets(90,5): error : NETSDKZZZZ: Error getting pack version: Pack 'Microsoft.Android.Runtime.25.android-x64' was not present in workload manifests. Additionally, the build has been updated to produce a reference pack for the API level declared in `$(AndroidDefaultTargetDotnetApiLevel)`, if it is not the same as `$(AndroidLatestStableApiLevel)`. This will allow the default `net6.0-android` target framework to use an up to date Mono.Android.dll, instead of an older preview version from NuGet.org.
