ci(rust): improve

Use action to install rust toolchain which also does some
workarounds / enables color.

Dont use old unmaintained action-rs actions, use in manually.
Downside: warnings get lost → deny everything and get a hard error.

With ring 0.17 out test platforms like risc-v or arm64 on windows.
