To make sure everything still compiles, we add a preliminary include of forward.h to tests.h to make sure it is included in every test source file. We'll clean up the tests.h includes in a later commit. We also add a <errno.h> include to errno-list.h to keep test-errno-list.c compiling. It'll be removed again when we clean up includes in src/basic. Split out of #37344.
