In golang.org/cl/209419, CheckPackageHandle was renamed to PackageHandle, but a number of references to CheckPackageHandle remained in function names and comments. This CL cleans up most of these, though there was at least one case (internal/lsp/cache.checkPackageKey) where the obvious renaming conflicted with another function, so I skipped it.
