[xaprepare] Move CMake file generation into a dedicated MSBuild project (#11760)

Continues the incremental dismantling of `xaprepare` (see #11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737, #11740). Two more generator methods come out, and the work they did moves into a small dedicated MSBuild project.

## What changes

Two xaprepare generators in `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs` are deleted:

* `Get_Cmake_XA_Build_Configuration` — produced `bin/Build$(Configuration)/xa_build_configuration.cmake`, included by `src/native/CMakeLists.txt`.
* `Get_Cmake_Presets` (and its `GetCmakePresetsCommon` helper) — produced `src/native/CMakePresets.json`, consumed by the `cmake` preset invocations in `src/native/native.targets`.

Both are now generated by a new project:

* **`src/native/cmake-config/cmake-config.csproj`** (`Microsoft.Build.NoTargets`) hosts `_GenerateCMakeFiles`, which uses the existing `ReplaceFileContents` MSBuild task to substitute the placeholders in `build-tools/scripts/xa_build_configuration.cmake.in` and `src/native/CMakePresets.json.in`.
* `native-mono.csproj`, `native-clr.csproj`, and `native-nativeaot.csproj` each `<ProjectReference>` this project.

### Why a dedicated project (not just a target in `native.targets`)

The three native csproj share two output files (`bin/Build$(Configuration)/xa_build_configuration.cmake` and `src/native/CMakePresets.json`). Hosting the generator in `native.targets` would either:

* Race on the shared outputs under parallel msbuild (`/m`), or
* Require a `'$(MSBuildProjectName)' == 'native-mono'` gate -- which breaks isolated `dotnet build native-clr.csproj` on a clean tree (the gitignored output files would never get generated).

A dedicated project with three incoming `<ProjectReference>`s solves both: single producer, and project-reference ordering guarantees the outputs exist before any consumer's `cmake` preset call -- including for isolated single-csproj builds.

### Incremental correctness

`_GenerateCMakeFiles` declares fully-anchored `Inputs`:

* `build-tools/scripts/xa_build_configuration.cmake.in`
* `src/native/CMakePresets.json.in`
* `Configuration.props` (`AndroidNdkDirectory`, `NinjaPath`, `MicrosoftAndroidSdkOutDir`, `XAPackagesDir`, `AndroidMinimumDotNetApiLevel`)
* `Directory.Build.props` (`TestOutputDirectory`)
* `eng/Versions.props` (`MicrosoftNETCoreAppRefPackageVersion`)

so editing any of those re-runs the target; a no-change rebuild skips it. (Note: `$(MSBuildAllProjects)` is intentionally **not** used -- it does not include imported `.props` files for SDK-style projects since MSBuild 16.0; verified empirically.)

### Cascading deletions in xaprepare

* `Configurables.NativeSourcesDir` (was used only by `Get_Cmake_Presets`).
* All eight `Configurables.Paths.NetcoreAppRuntimeAndroid*` / `CoreClrAppRuntimeAndroid*` properties (+ backing fields + the `GetNetcoreAppRuntimePath` / `GetCoreClrAppRuntimePath` helpers) -- the new MSBuild target reads `$(XAPackagesDir)` / `$(MicrosoftNETCoreAppRefPackageVersion)` directly.
* The `Get_Cmake_*` entries in `Step_GenerateFiles.GetFilesToGenerate`.

`BuildAndroidPlatforms.NdkMinimumAPI` / `NdkMinimumAPILegacy32` are kept -- still used by `Get_XABuildConfig_cs` (a separate generator for a future PR).

### What stays

The `.in` template files are unchanged and still tracked in git -- the new MSBuild target reads them. The other generators in `Step_GenerateFiles.cs` (`Get_SourceLink_Json`, `Get_Configuration_OperatingSystem_props`, `Get_XABuildConfig_cs`, `AddOSSpecificSteps`) are out of scope and untouched.

## Verification

On Windows:

* `build.cmd Prepare -c Debug`
* `dotnet-local.cmd build src\native\native-mono.csproj -c Debug` -> 0 errors, generates both files
* `dotnet-local.cmd build src\native\native-clr.csproj -c Debug` -> 0 errors (incl. clean-tree isolated build)
* `dotnet-local.cmd build src\native\native-nativeaot.csproj -c Debug` -> 0 errors
* `dotnet-local.cmd build build-tools\xaprepare\xaprepare\xaprepare.csproj -c Debug` -> 0 errors

Incremental behaviour verified by walking through MSBuild diagnostic output:

* No-change rebuild: `Skipping target "_GenerateCMakeFiles" because all output files are up-to-date`.
* `touch eng/Versions.props` + rebuild: `Building target "_GenerateCMakeFiles" completely`, outputs re-written.

The generated `CMakePresets.json` and `xa_build_configuration.cmake` were diffed against the xaprepare baselines captured before the deletion; only the path separator normalisation (forward slashes throughout) differs, which both CMake and JSON accept on every platform.
