This CL changes the toolchain selection behavior for go install pkg@v and go run pkg@v to also take into account the go and toolchain version lines in the containing go.mod and go.work file. Before this change, the go command would detect that go install pkg@version or go run pkg@version was being run and skip the standard behavior that would select the toolchain based on the go version in the go.mod or go.work file. It would instead check the go line of the module being downloaded and switch to that version if necessary. With this change, the go command does not skip the standard behavior. It proceeds to determine if an upgrade is required based on the containing go.mod or go.work file's go and toolchain lines. Then, it checks the module being installed to see if it would require a higher version than the determined upgrade (or the local version if no upgrade was determined). If it does require a higher version, then a switch happens to that version, and if not the upgrade logic proceeds as usual doing the upgrade if one was determined.
