Slight cleanup of file locations in flutter_tools
to make it easier to see which files are responsible
for data reporting.

This updates the flutter tool cache to download binary files for ideviceinstaller, ios-deploy, libimobiledevice, and dynamically linked dependencies from Flutter's GCP bucket.

This reverts commit 14d489ad.

Disable CocoaPods input and output paths in Xcode build phase and adopt new Xcode build system (#34167)

Updates the Podfile template to use the CocoaPod disable_input_output_paths installation option which prevents the [CP] Embed Pods Frameworks build phase from outputting the Flutter.framework files.

Moves the logic for finding vcvars64.bat to a new VisualStudio class
that encapsulates finding, and providing information about, VisualStudio
installations. Adds a validator for it, and runs it for Windows
workflows in doctor.

This reverts commit 0d79f0fc.

Splits Xcode validation out of the iOS validator and into a stand-alone
validator, and groups the CocoaPods validator with that top-level
validator instead of the iOS validator. iOS now validates only the
iOS-specific tools (e.g., ideviceinstaller).

Reorganizes many of the associated clases so that those that are used by
both macOS and iOS live in macos/ rather than ios/. Moves some
validators to their own files as part of the restructuring.

This is the macOS portion of #31368

This reverts commit e5459942.
