[build] Update stable Android SDK packages

[jonathanpeppers]

Summary

• update stable Android SDK tools, emulator, CMake, sources, and existing platform package revisions
• add architecture-specific command-line tools support for Apple Silicon
• retain Android NDK r28c and Android platform 37.0 without adding newer API levels
• update all affected SHA-256 package hashes
• keep Android sources in the API-level directory expected by the build
• fix CMake 4 source-path quoting for Windows native builds
• track every substituted SDK property in a content-based cache so shipped SDK metadata is regenerated when package versions change
• isolate workload installation from persistent NuGet caches and pre-seed it from the SDK package produced by the current build, preventing reused PR versions from resolving older same-version feed content
• omit the optional AVD device profile unless explicitly configured because command-line tools 22 rejects the API 29 system image's absent devices.xml

Testing

• dotnet build .\build-tools\Xamarin.Android.Tools.BootstrapTasks\Xamarin.Android.Tools.BootstrapTasks.csproj -v:minimal
• dotnet build .\src\androidsdk\androidsdk.csproj --no-restore -v:minimal
• dotnet build .\build-tools\Xamarin.Android.Tools.BootstrapTasks\Xamarin.Android.Tools.BootstrapTasks.csproj -c Release -v:minimal
• dotnet build .\src\native\cmake-config\cmake-config.csproj -c Release -v:minimal
• built native-mono.csproj from clean outputs with CMake 3.30.3 and 4.1.2 using NDK r28c; all 28 .so outputs across four ABIs had identical sizes and SHA-256 hashes
• exercised the Windows native CMake configure target through RunParallelCmds; preset discovery succeeded with CMake 4.1.2
• verified _GenerateXACommonProps regenerates an existing SDK props file across a simulated build-tools 36.0.0 → 37.0.0 transition
• inspected the exact dependency, binding, workload-extraction, and emulator binlog attachments from Azure builds 1552260, 1552452, 1552621, 1552729, and 1552892
• confirmed all SDK packages produced by build 1552892 contain build-tools 37.0.0; its workload binlog showed both the PR SDK and released 36.1.69 packs being installed, identifying stale same-version feed content as the remaining metadata source
• reproduced command-line tools 22 AVD creation against the exact API 29 r08 system image: --device pixel_4 emits the CI devices.xml errors, while omitting it succeeds cleanly
• verified a PackageDownload restore from the current build artifact seeds an isolated NuGet package cache with SDK metadata containing build-tools 37.0.0

Pull request overview

Updates the in-repo Android SDK “bootstrap” package catalog used by src/androidsdk/ so the toolchain downloads (platforms, tools, emulator, CMake, sources) match newer stable revisions, including introducing separate macOS command-line tools archives per architecture.

Changes:

• Bumped platform package revisions (API 28–37) and updated corresponding SHA-256 hashes.
• Updated toolchain component versions/hashes (build-tools, platform-tools, command-line tools, emulator, CMake) and added a macOS arm64 command-line tools package entry.
• Switched the downloaded “sources” zip to the latest stable platform revision.
