Building on #3504 this update further refactors tool_yml to make it easier to author by splitting each yml file generation into a separate module. Some minor tweaks to yml generation are also included:

• Clippy now checks everything except the test crates since they're too noisy and have intentional test code that Clippy doesn't like. Automate yml workflow generation for MSRV checks #3504 reduced clippy coverage to just libs but I realized that some tools and samples can benefit from Clippy validaiton.
• The clippy and no-default-features yml workflows are simplified by removing the unnecessary strategy matrix since those only run on nightly-x86_64-pc-windows-msvc.
