improve build times by extracting asset opt into its own crate (#3273)

* improve build types by extracing asset opt as a dylib
* dont use dylib, but let regular workspace caching do the heavy lifting
* add prebuild to cli for better lock contention
* hoist deps
* disable slow tests
* re-enable sequential, debug=0 for dev
* use vfs for windows
* dont cache on failure, fix windows vfs caceh
* free disk space re-order
* add clippy + fmt to windows channel
* yoink makefile
* proper rustfmt/clippy on toolchain
* set incremental to zero since cargo-cache disables it
