consuming the new project endpoint.

also deprecating the old platformio and npmDependencies fields in pxt.json since we don't actually use them anywhere; i think they were mostly just for testing new hardware builds

🟡 Changes recommended

Critical regressions exclude required native build inputs from requests and hashes, break project include paths and simulator-only compilation, and leave the new CLI tests unable to type-check.

What changed in this PR

Updates PXT’s native compilation pipeline to consume the new project-based cloud endpoint, with shared request preparation for compiler and backend use.

Changes:

• Adds canonical native-project payloads and hashes.
• Uses the project compile endpoint, checks both hex cache locations, and fetches the returned build URL.
• Removes support for package-level npmDependencies and platformio, with warnings, documentation, and request-focused tests.

this is technically a breaking change, but one that will only affect extension authors and not end-users. and i think it's pretty unlikely to affect the extension authors either; only if they were prefixing their includes with the name of their extension
