feat: reference sketch.yaml platforms for "upload", "board list", etc. #2602
Description
Describe the request
The sketch project file sketch.yaml is wonderful for making more self contained projects that don't include the dreaded "okay now here follow these 20 steps to Set Up Your Machine, by the way they're out of date" disease. (Version managers like asdf or mise are another part of the solution.)
BUT it only really has much effect for arduino-cli compile. When for example doing arduino-cli upload, if the core in question hasn't been installed with arduino-cli core install, the upload will often fail. Similarly, arduino-cli board list won't detect boards unless the core has been installed.
The upload command does parse sketch.yaml to find attachment information, so, there's some precedent for looking for one...
Describe the current behavior
A core that is referenced in sketch.yaml but not globally installed on the system doesn't inform arduino-cli upload or arduino-cli board list commands.
