Matthew Dempsky dfdf55158d cmd/compile/internal/noder: fix type switch case vars package 
When naming case variables, the unified frontend was using
typecheck.Lookup, which uses the current package, rather than
localIdent, which uses the package the variable was originally
declared in. When inlining across package boundaries, this could cause
the case variables to be associated with the wrong package.

In practice, I don't believe this has any negative consequences, but
it's inconsistent and triggered an ICE in typecheck.ClosureType, which
expected all captured variables to be declared in the same package.

Easy fix is to ensure case variables are declared in the correct
package by using localIdent.

Fixes #54912.
