Make the full target set buildable on Linux/macOS, not just Windows:
- Set EnableWindowsTargeting=true and drop the Windows-only gate on the
net462/net472/net481 legacy targets so they are always part of the build.
- Always include the net8/9/10 -windows TFMs in the UI projects' target set.
- Drop the IsOsPlatform('Windows') gate on Splat.Drawing's UseWPF/UseWindowsForms
(and its redundant local EnableWindowsTargeting) so the WPF/WinForms reference
packs are restored and the desktop TFMs reference-compile everywhere.
- Apple TFMs remain gated to Windows/macOS (they cannot build on Linux).
Verified on Linux: core + Splat.Drawing build across net8.0/net9.0/net10.0/
net462/net472/net481 and the -windows TFMs; full test suite passes (12825 passed, 0 failed).
Android TFMs were bare (`net9.0-android`/`net10.0-android`) with no platform
version. When Splat.Drawing is consumed via a cross-repo ProjectReference the
platform version is not resolved during restore, producing NU1012 ("Platform
version is not present for one or more target frameworks").
- Pin the versions: `net9.0-android35.0;net10.0-android36.0`.
- Update Splat.Drawing's Android `<ItemGroup>` condition from
`EndsWith('0-android')` (which no longer matches the versioned TFM) to the
version-agnostic `GetTargetPlatformIdentifier(...) == 'android'`, so the
Android `PlatformBitmapLoader` is still compiled in.

What
Two build/targeting fixes so the full Splat target matrix restores and reference-compiles on non-Windows machines.
1. Compile .NET Framework and Windows targets on non-Windows
EnableWindowsTargeting=trueso the WPF/WinForms/.NET Framework reference packs restore on any OS.IsOsPlatform('Windows')guards around the legacy (net462/net472/net481) and Windows desktop TFMs, and aroundUseWPF/UseWindowsFormsinSplat.Drawing, so those desktop TFMs reference-compile on Linux/macOS as well as Windows.2. Pin Android target platform versions
net9.0-android/net10.0-androidwere bare (no platform version). WhenSplat.Drawingis consumed via a cross-repoProjectReference, the platform version is not resolved during restore, producingNU1012("Platform version is not present for one or more target frameworks"). Pinned tonet9.0-android35.0;net10.0-android36.0.Splat.Drawing's Android<ItemGroup>condition fromEndsWith('0-android')(which no longer matches the versioned TFM) to the version-agnostic$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'android', so the AndroidPlatformBitmapLoaderis still compiled in.Why
ReactiveUI temporarily project-references the local Splat / Splat.Drawing while the dead
System.Reactivedependency is removed. These changes let that full target matrix build on non-Windows CI and dev machines.
