Isolate the biggest CIPD assets to trim down on overhead This change, when combined with https://skia-review.googlesource.com/c/buildbot/+/77701 should cut down on the duplicated work of extracting the large toolchains from CIPD. Since the Isolate* steps can be cached (i.e. are idempotent) they will only run about 1/week (unless updated) and all subsequent tasks (primarily Builds) will go much faster. We estimate the overhead on Build-Debian-Android to go from about 90s (which was more time than the actual build) to about 10s. Build-Win-Vulkan's overhead will improve from about 180s to about 35s (1/3 of which is uploading to isolate). Other CIPD assets could be handled in a similar fashion; the ones here are the biggest offenders and the lowest hanging fruit. Doing this to other assets (e.g. clang_win) would have minimal improvements (<10s). There are other tasks with large amounts of overhead (e.g. Build-Mac-Android, Build-Win-Android, Build-WASM) but none of those are depended on by any Tests, so any speed-ups would have less wide-reaching-impact, at the cost of using more Isolate cache/diskspace.
