This patch introduces `BrowserFetcher` class that manages downloaded versions of products. This patch: - shapes Downloader API to be minimal yet usable for our needs. This includes removing such methods as `Downloader.supportedPlatforms` and `Downloader.defaultRevision`. - makes most of the fs-related methods in Downloader async. The only exception is the `Downloader.revisionInfo`: it has stay sync due to the `pptr.executablePath()` method being sync. - updates `install.js` and `utils/check_availability.js` to use new API - finally, renames `Downloader` into `BrowserFetcher` Fixes #1748.
