BOOT_TAG lived shortly in sys/msgbuf.h, but this wasn't necessarily great for changing it or removing it. Move it into subr_prf.c and add options for it to opt_printf.h. One can specify both the BOOT_TAG and BOOT_TAG_SZ (really, size of the buffer that holds the BOOT_TAG). We expose it as kern.boot_tag and also add a loader tunable by the same name that we'll fetch upon initialization of the msgbuf. This allows for flexibility and also ensures that there's a consistent way to figure out the boot tag of the running kernel, rather than relying on headers to be in-sync.
