[dev.regabi] cmd/compile: cleanup //go:generate directives

During recent refactoring, we moved mkbuiltin.go to package typecheck,
but accidentally duplicated its //go:generate directive into a bunch
of other files/directories. This CL cleans up the unnecessary
duplicates.

Also, update all of the stringer invocations to use an explicit file
name, and regenerate their files.

Updates #43369.
