Description

There are a few places in Naga where we actually clone an Arena, in situations where a take would be better. For example, naga::front::wgsl::lower::Lowerer::lower clones the diagnostic filters array.

Contributor guide

Research direction
Examine the Arena type in Naga to determine if a take method can be added. Look at the usage in naga::front::wgsl::lower::Lowerer::lower and other places where Arena is cloned. Implement a take method that removes and returns data, and replace clones with take calls. Ensure all tests pass.
