CS1504 with AndroidBoundLayout when building with .NET 8 SDK

### Android application type

.NET Android (net7.0-android, etc.)

### Affected platform version

VS 2022 17.8

### Description

After upgrading to VS2022 17.8, I cannot build my .NET 7 Android app anymore. Same issue with `dotnet build`.

For every Android layout file with build action 'AndroidBoundLayout', I'm getting the build error:

`project\obj\Debug\net7.0-android33.0\generated\Binding.About.g.cs(27,11): error CS1504: Source file 'Resources\Layout\About.xml' could not be opened -- Could not find file.`

The generated .cs file contains code `#line 2 "Resources\Layout\About.xml"` which seems to break compiling.

### Steps to Reproduce

Use .NET 8 SDK to build a project with AndroidBoundLayout file.
