ci: use rustup-init instead of tarball This is done because the tarball does not include rust-src. ci: parameterized ZTS/NTS for build_profiler task

Description
Recently the build artifacts got quite large due to the tracer including debug symbols for things. The profiler has also been creeping up in size, and so I thought I'd try to shrink the build artifacts. These all seem to individually give small decreases in size:
codegen-units=1lto="fat"debug="line-tables-only"panic=abort-Z build-std="panic_abort,core,alloc,std". However, this requires nightly, to avoid this, we use theRUSTC_BOOTSTRAP=1hack.Note that if you are buliding locally to try to reproduce savings, we also compress with
objcopy --compress-debug-sectionsafterwards.Reviewer checklist
