ci: Run clang tidy checks for each PR

[jackgerrits]

• Since checks will be required to pass they should be scoped back. I suggest we just start with the decided coding guideline of braces required for every block
• Will not pass until the checks are fixed in master

i guess we don't foresee any changes where this would make a difference?

This resolves the lint of moving a trivially copyable type having no effect. If this object becomes non-trivial where the move would be necessary then this CI will tell us because of the performance-unnecessary-copy-initialization check.

[peterychang]

one nit: If you're gonna remove the std::move calls, maybe add a comment somewhere noting that ec.l.cs contains a vector so std::move is necessary, whereas ec.l.multi is a POD type so its unnecessary

[jackgerrits]

That's kind of the point in making this an automated check though - we can enforce that it is done right in case we forget to check the type before copying/moving

[jackgerrits]

Updated to allow for moving trivially copyable types to avoid this confusion.
