Add .clippy.toml to lint MSRV

[rustaceanrob]

Allows clippy to catch and lint violations of the MSRV without further LSP configuration

Hmm, I'd rather consider setting the rust-version field in Cargo.toml, which, IIUC, should also work?

In SV2 project the rust-version was used and caused rust-analyzer to not work with some text editors unless you edit the config within the text editor to align the versions(or with $ rustup use [MSRV]), which becomes annoying if you switch between different projects with different MSRV's. Not sure about the .clippy file though as we are not using it.

Huh, shouldn't it just be an issue for older versions? FWIW, building with a newer version than the given rust-version works fine?

For me, if I configure rust-analyzer to use stable toolchain in vim and specify a different version in Cargo.toml, rust-analyzer wont work in vim. Other people in the team reported similar issue with different text editor also.

Alright, going ahead and merging this.
