m68k: kernel: Add and use "vectors.h"

When building with W=1:

    arch/m68k/kernel/vectors.c:52:13: warning: no previous prototype for ‘base_trap_init’ [-Wmissing-prototypes]
       52 | void __init base_trap_init(void)
	  |             ^~~~~~~~~~~~~~

Fix this by introducing a new header file "vectors.h" for holding the
prototypes of functions implemented in arch/m68k/kernel/vectors.c.
