Rollup merge of #133418 - Zalathar:spans, r=jieyouxu 
coverage: Store coverage source regions as `Span` until codegen

Historically, coverage spans were converted into line/column coordinates during the MIR instrumentation pass.

This PR moves that conversion step into codegen, so that coverage spans spend most of their time stored as `Span` instead.

In addition to being conceptually nicer, this also reduces the size of coverage mappings in MIR, because `Span` is smaller than 4x u32.

There should be no changes to coverage output.
